Again for those not subscribed to mercury-bugs:

Said C code needs to be used with a version of the Boehm garbage
collector compiled with -DALL_INTERIOR_POINTERS.
This is mentioned in the documentation in the mercury_tcltk directory,
which I hadn't read until this week, after isolating the trigger of the
bug to mercury_tcltk code.  I don't know why this segfault seems to
occur only with hlc.

The mercury_tcltk documentation suggests recompiling the libgc from the
Mercury distribution, though so far things seem to work if one just uses
LD_PRELOAD=<a default build of a standard libgc install>.
