------- Comment #1 from ebotcazou at gcc dot gnu dot org 2009-11-03 18:49 -------
Somewhat expected, see the comment in the test. A patch to disable it on this
platform (sparc*-*-solaris2.11) is pre-approved.
The failure very likely means that the 64-bit pattern matching code of the
fallback routine in config/sparc/sol2-unwind.h misbehaves for Solaris 11.
Unfortunately, I don't have access to any Solaris 11 machine so I cannot fix.
To debug this, you need to recompile libgcc at -O0 -g and put a breakpoint on
sparc64_fallback_frame_state from within the debugger; it will be hit once you
resume execution after the SIGSEGV. What happens from that on?
