[tex-live] mf segfault

       mf "\mode=proof; \input feta20"

FWIW, this does seg fault for me on red hat 9 (libc 2.3.2, it seems),
after less than five minutes at "classical quarter rest".

On red hat ws 2.1 (libc 2.2.4), it also crashes, although it takes a bit
longer.  

On sparc-solaris 2.8, also crashes, after about 10 minutes.

Maybe the timing is somehow related to system configuration.

Memory use (RSS) increases as it spins, but it doesn't seem to get
enormously huge.

Hmm.  Will need to compile with -g and see what's happening.

Thanks for reporting it.  (But *sigh* for all these seg faults!)
