I think it is tripping on raise/abort() in one of these routines, but
nothing is printing that information.  See below.

Ah, thanks.  I missed this.  mdmfs(8) has a bug in its run() function.
It treats programs that exit with a signal (KILL, ABRT, ILL, SEGV...)
the same as programs that exit with success.  This is a (major)
problem and the reason raise/abort is not visible.

Best,
