This bug was observed for the lrem instruction and the ldiv instruction too, but not for ladd or lsub. Finally, note that it appears only when using the inlined-threaded-interpreter, but not with the direct or indirect-threaded-interpreter. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105523&aid=434181&group_id=5523 |

Bugs item #429958, was opened at 2001-06-04 00:06 You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105523&aid=429958&group_id=5523 Category: Execution Problem Group: SableVM >Status: Closed Resolution: Fixed Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Etienne M. Gagnon (egagnon) Summary: Abortion on Linux 2.4 Initial Comment: Thank you for your great VM. SableVM is easier to understand VM architecture. I found a problem of abortion on VM. The abortion takes place on Linux kernel ver. 2.4. The cause is at about line number 97-99 in interpreter.c, following context; locals = (_svmt_stack_value *) (((char *) frame) - method->locals_size); Inspite of the value of 'method' is set NULL, 'locals_size' points c3 on my environment. I can avoid this problem by using if statement, like this, if (method != NULL) { locals = ... stack = ... } -- Hiro ISHIKAWA Graduate School of Science and Engineering, Waseda University ---------------------------------------------------------------------- Comment By: Etienne M. Gagnon (egagnon) Date: 2002-08-06 01:06 Message: Logged In: YES user_id=15365 The new code fixes this bug and many others.

Gagnon (egagnon) Date: 2001-06-08 16:11 Message: Logged In: YES user_id=15365 This is effectively a bug. method->locals_size doesn't dereference NULL when "method" is NULL, because the offset of locals_size is added to it. We must cause the segmentation fault using a NULL dereference. Will be fixed. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105523&aid=429958&group_id=5523 |

Bugs item #422564, was opened at 2001-05-09 03:12 You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105523&aid=422564&group_id=5523 Category: Execution Problem Group: SableVM >Status: Closed >Resolution: Fixed Priority: 8 Submitted By: Navindra Umanee (navindra) Assigned to: Etienne M. Gagnon (egagnon) Summary: Switch statement not handled correctly Initial Comment: Aha! Found my second or third SableVM bug -- finally one that's easy to describe and reproduce. ;-) Check the attached .java file, and compile it. Run it against Sun Java and SableVM: [asimov] [/home/navindra/work] java SableVMBug Switch1: 1 [asimov] [/home/navindra/work] sablevm -Y SableVMBug Switch1: default While debugging coffi, I at first thought this bug involved nested switches but the simplicity of this included example proves otherwise and muchly confuses me. It appears that sometimes switches work and sometimes not. I'll look into this some more if it'll help. ---------------------------------------------------------------------- >Comment By: Etienne M. Gagnon (egagnon) Date: 2002-08-06 01:04 Message: Logged In: YES user_id=15365 The new code fixes this bug and many others. ---------------------------------------------------------------------- Comment By: Navindra Umanee (navindra) Date: 2001-05-09 03:59 Message: Logged In: YES user_id=210140 It's more interesting than I thought. The problem exhibits itself if one uses the Sun Java compiler to compile the attached file, but not if one uses the Jikes compiler with the SablePath libraries. The most interesting difference in the compiled code is that Jikes uses a Tableswitch where javac uses a Lookupswitch. Hmmm. Must sleep. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105523&aid=422564&group_id=5523 |

You will probably need to rename the generated library file and links from libgmp.so* to libgmp2.so* 3- If this does not work for you, you can get the sources from the ftp.gnu.org, and compile it on your system.

Could I get a copy of the file you used? It might be running up against some internal constraint of the fgets function, in which case we'll have to re-implement using fgetc. However, I suspect there's some parsing issue with the line-based reads and realloc's.

Gagnon (egagnon) Summary: Switch statement not handled correctly Initial Comment: Aha! Found my second or third SableVM bug -- finally one that's easy to describe and reproduce. ;-) Check the attached .java file, and compile it. Run it against Sun Java and SableVM: [asimov] [/home/navindra/work] java SableVMBug Switch1: 1 [asimov] [/home/navindra/work] sablevm -Y SableVMBug Switch1: default While debugging coffi, I at first thought this bug involved nested switches but the simplicity of this included example proves otherwise and muchly confuses me. It appears that sometimes switches work and sometimes not. I'll look into this some more if it'll help. ---------------------------------------------------------------------- Comment By: Navindra Umanee (navindra) Date: 2001-05-09 00:59 Message: Logged In: YES user_id=210140 It's more interesting than I thought. The problem exhibits itself if one uses the Sun Java compiler to compile the attached file, but not if one uses the Jikes compiler with the SablePath libraries. The most interesting difference in the compiled code is that Jikes uses a Tableswitch where javac uses a Lookupswitch. Hmmm. Must sleep. ---------------------------------------------------------------------- You can respond by visiting: http://sourceforge.net/tracker/?func=detail&atid=105523&aid=422564&group_id=5523 |
