The following is a test for the change I recently made to allow macros to
continue operating even after a backtrace failure occurs.
Tested on x86-linux with linuxthreads and ia64-linux with nptl threads.
Ok to commit?

Can you think of an alternative to "macro" as the prefix? "macro" can
also refer to:
#define MACRO
(If I new of one, I'd suggest it :-) With a better name, ok.
