Sorry to bother everyone if this is already noted somewhere but I couldn't find it if so. My environment is as follows: * Red Hat Enterprise Linux AS release 3 (Taroon Update 3) * 2.4.21-27.0.2.ELsmp * valgrind-2.4.0 I have a very large app that uses a number of libs and a lot of memory management. I'm trying to suppress everything except what is in my app and the resulting suppressions file is: * 169,000 lines * 10,400 entries When I try to use it with valgrind I get a very quick abort in a malloc (and I'm not able to get gdb to localize the abort). If I reduce the file to 10,000 lines and around 700 enties valgrind will run. I've looked at the code and the list archives and help files and I don't see any specific limitation on the number of suppression entries (other than physical memory). Is there a guideline on the max size of suppression files? tks for any help agg |

However, I doubt anyone has stressed the suppression mechanism this much so it's not that surprising that something goes wrong. Can you try your big suppression file with small test programs, and see if that causes problems? That would be an interesting test. Why do you need 10,000 suppressions? I've not heard of anyone needing more than a few hundred (and here's everyone else's chance to enlighten me about how many suppressions they have). N |
