thanks. I'll give that a try. I downloaded the dmalloc package, but that
is another case
of trying to hack a makefile, and work my way through the heavily unix
oriented docs before
I'll get anything out of it.

I did get a libdmalloc.a built, linked it in in place of the malloc, and
MC doesn't fault under it.
I am reasonably sure MC is corrupting 'fenceposts', but haven't figured
out yet how to get dmalloc
to check and log those errors.

There is a note in the dmalloc package saying not to be too surprised if
many unix programs are found
to hit the fenceposts. This does not sound good.
