It just now occurred to me that I can install some *-dbg packages to
get debugging symbols.
Here are the backtraces from two recent core dumps:
Program terminated with signal 6, Aborted.
(gdb) bt

#13 0xb7e77bee in clone () from /lib/libc.so.6
(This is the same backtrace I reported earlier, without symbols.)
Program terminated with signal 11, Segmentation fault.

#10 0xb7ee7bee in clone () from /lib/libc.so.6
(This is a new backtrace from a more recent crash.)
Looks like some kind of memory corruption, perhaps... I'll do a bit
more investigation and report more if I discover anything further.
