[tex-live] mpost segfault

[Karl Berry]

    No idea what's wrong. A compiler problem?

I tried recompiling it on tug.org, using a different version of gcc,
without optimization.  It still crashed.

Gdb shows that it happens in dospecial, at mp2.c, line 1911.
The line is this:
 mem [lastpending ].hhfield .v.RH = stashcurexp () ;

lastpending is 2499996, which is apparently garbage -- "cannot access
memory at address".

Taco, help??!!!

Thanks,
Karl

P.S. mandala.mp processes fine with plain.mem.
