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:
