6.4 works, but I've found that no matter what, initializing the following:

1. mutex attribute type
2. thrad attribute type

results in a SIGSEGV.

mutex and condvars no longer result in a visible SIGSEGV with one of the newer
snapshots and 6.4. Also, I've found a better method which is:

handle SIGSEGV noprint nostop
handle SIGTRAP noprint nostop

Another method I've taken is to dynamically initialize all mutexes, attributes,
and condvars. But really I should have to do *any* of the above to debug code,
as they are mediocre solutions.
