signal 11 crash ChangeLog 1.2178

[David Bobroff]

Updated from CVS to ChangeLog 1.2178.  Got this on a file which had run
just fine before (as of ChangeLog 1.2175):

lilypond: error: LilyPond crashed (signal 11).

Then I followed instructions Han-Wen sent me some time ago to do a
stack-trace.  This is what I got:


Program received signal SIGSEGV, Segmentation fault.
