I have upgraded to gcc version 4.0.0 20041127 (experimental) and my app now
receives this:
Program received signal SIGSEGV, Segmentation fault.

There were recent changes to the THREAD_LOCAL_ALLOC define I believe. Whether
related or not I'm not sure.
<builddir>/i686-pc-linux-gnu/libjava/include/java-gc.h (is a symlink to
/libjava/include/boehm-gc.h)
#ifdef THREAD_LOCAL_ALLOC
return GC_local_gcj_malloc (size, klass->vtable); // this is line 46
