a little different.

Well, that confirms the thought that the memory context is clobbered,
but we're not any closer to understanding why.

gdb can find them.

Dang it. I wonder why the --enable-debug option doesn't seem to actually
be enabling debug. :( For reference, here is the configure command that
the package uses according to the config.log (in case you spot anything
wrong).

I'm going to try a compile from scratch from the 8.1.15 source tarball
and see if I can get better results. I'll let you know (probably next
week). Thanks.
