[Bug java/18699] New: [4.0 Regression] SIGSEGV in GC_local_gcj_malloc

["ovidr at users dot sourceforge dot net" <gcc-bugzilla at gcc dot gnu dot org>]

I have upgraded to gcc version 4.0.0 20041127 (experimental) and my app now
receives this:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 1103858608 (LWP 4735)]

my_entry = Variable "my_entry" is not available.


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
#else
  return GC_gcj_malloc (size, klass->vtable);
#endif
