[Sablevm-user] crash in FindClass() from sablevm/sablevm.c

Hello, I recently downloaded 1.0.3 of sablevm, the native class package, and the classes package. I put them all in /usr/local/src and unpacked them there, downloaded/built/installed libffi-1.20, then as root ran [root@basalt /usr/local/src]# ./sablevm-1.0.3/build-many And everything seemed to work fine. However, I can't seem to get the vm to run any java ;) The gdb session/backtrace follows. It looks like it's dying while trying to find the java.lang.String class in order to build the array of argv for the main() method call. If I run the non-debug version of sablevm outside the debugger, it just hangs. Has anyone else had similar problems? Any tips? thanks, -emile ------------------------------------------------------------------- backtrace stuff. (Echo is a 'hello world' style java class that I tried compiling with both jikes 1.16 and gcj 2.96.) ------------------------------------------------------------------- [esnyder@basalt ~/dev/test]$ gdb /usr/local/bin/sablevm-debug (gdb) run Echo Starting program: /usr/local/bin/sablevm-debug Echo [New Thread 1024 (LWP 17889)] SableVM version 1.0.3 Copyright (C) 2000-2002 Etienne M.
