+Summary: Segfault on PPC when using a libgcc_s/libpthread compiled with SSP
+
+Description of Problem:
+
+
+
+Steps to reproduce the problem:
+1. Compile libgcc_s (gcc) and libpthread (glibc) with SSP
+2. Run mono or compile it
+
+Actual Results:
+Weird segfaults
+
+Expected Results:
+mono working
+
+How often does this happen?
+Always
+
+Additional Information:
+this is with glibc 2.4, gcc 4.1.1 and mono 1.1.13.8.
+
+When using a mono only with SVN rev 61756 one gets:
+if test -w ../mcs; then :; else chmod -R +w ../mcs; fi
+cd ../mcs && /usr/bin/make PROFILES='default net_2_0' CC='gcc' all-profiles
+make[4]: Entering directory `/build/buildd/mono-1.1.13.8/mcs'
+/usr/bin/make profile-do--default--all profile-do--net_2_0--all
+make[5]: Entering directory `/build/buildd/mono-1.1.13.8/mcs'
+/usr/bin/make PROFILE=basic all
+make[6]: Entering directory `/build/buildd/mono-1.1.13.8/mcs'
+make[7]: mcs: Command not found
+make[7]: *** [build/deps/basic-profile-check.exe] Error 127
+make[7]: Entering directory `/build/buildd/mono-1.1.13.8/mcs'
+*** The compiler 'mcs' doesn't appear to be usable.
+*** Trying the 'monolite' directory.

+
+=================================================================
+Got a SIGSEGV while executing native code. This usually indicates
+a fatal error in the mono runtime or one of the native libraries
+used by your application.

+=================================================================
+
+Stacktrace:
+[and so on]
+
+
+Running in gdb shows that the mono segfault handler dereferences a null
+pointer in mono_jit_walk_stack() in exceptions-ppc.c:
+ MonoJitTlsData *jit_tls = TlsGetValue (mono_jit_tls_id);
+ MonoLMF *lmf = jit_tls->lmf;
+
+jit_tls is NULL.
+
+This seem to be partially fixed by replacing the g_malloc() in
+mono_debugger_create() (tramp-ppc.c) and mono_arch_emit_prolog()
+(mini-ppc.c) by mono_global_codeman_reserve(). (Thanks to Johannes Berg for
+noticing this).
+
+There's still a segfault but now one gets useful output:
+
