When compiling lily, you should pass option

--enable-debugging

to ./autogen.sh or ./configure (whatever you use) to keep debugging 
symbols in lilypond-bin.  Similarly, if you compile guile by yourself, it 
may a good idea to turn on debugging symbols on it as well.

Do not forget to load the core dump file into gdb, e.g.

(gdb) core core.7125

If your shell does not produce a core dump file in the current 
directory (it should say something like "Signal 11 (core dumped)" or 
similar), then you probably have the core dump limit set wrong.  I 
recommend to set it to at least 15 MByte (e.g. by "limit core 15M" in 
tcsh; in bash the command is called "ulimit").  After loading the core 
file into gdb, try:

(gdb) bt full

to produce a full backtrace.


Jan / Han-Wen:  On the current lilypond site, is there somewhere a guide 
how to report bugs?  If yes, it's well hidden, as I could not immediately 
find it.  If no, the above description or something similar should be 
added.
