pa32_fallback_frame_state should have taken care of this.

> pa32_fallback_frame_state should have taken care of this.

Possibly, there is a bug there.  However, the enclosed change 
appears to fix libgcj/23507 and partially fixes this PR.  There
appears to be a typo which doubles state->length in stacktrace.cc.
This causes memcpy to segfault.  The character of the fails changes
when this is fixed:

GC Warning: Out of Memory!  Returning NIL!
WARNING: program timed out.
FAIL: PR218 execution - source compiled test
UNTESTED: PR218 output - source compiled test

The fix for libgcj/23507 is to use a function pointer comparison
in the compare that tries to detect the interpreter.

I think this bug is probably a target issue.  The unwind process gets
stuck after unwinding through the signal handler:
