 I think valgrind would be the most useful thing.  Also, it'd be nice to
 see how this binary was built and if anything changes if built with -O0;
 since that line doesn't look like there's any very clear possible cause,
 and the circuitmux.c in the Debian repo matches ours, I'd be curious to
 see if the actual crash was elsewhere and the optimizer has confused
 things.  Since so far the exact site of the crash seems nondeterministic,
 though, we may not see this again if the reporter re-runs with a different
 build.
