[Gc] segfault with CACAO on OpenSolaris

[Christian Thalinger]

Hi!

I tried to get CACAO, which uses Boehm-GC 7.1, running on my x86_64
OpenSolaris box and sometimes the GC crashes like this:

  ---- called from signal handler with signal 11 (SIGSEGV) ------
  [16] GC_malloc(bytes = 32U), line 179 in "thread_local_alloc.c"
  [17] heap_alloc(size = 32U, references = 524288, finalizer = (nil), collect = true), line 153 in "gc-boehm.cpp"
  [18] builtin_new(c = 0x48cb00), line 879 in "builtin.c"
  [19] jni_NewObject(env = 0x413e60, clazz = 0x48cb00, methodID = 0x9bad40, ...), line 1301 in "jni.cpp"
  [20] Java_java_lang_VMProcess_nativeSpawn(env = 0xfffffd7ffee22200, this = 0x575060, cmdArray = 0x594a80, envArray = (nil), dirFile = 0xb, redirect = '\0'), line 235 in "java_lang_VMProcess.c"

A lot of program work though.  It seems it's somehow related to JNI
calls, but that's just a guess.  The same programs work on x86_64
GNU/Linux compiled from the same source code base.

Any idea what could be the problem?
