Yes, that's what would happen if LilyPond were causing the segfault. It
appears to me that gdb is creating the segfault.

I had not. I also hadn't realized that --enable-debugging is on by default.
So I disabled optimization, and reran make.
Same result, unfortunately.
However, on a hunch I decided to look at the .gdbinit file. I had been
using the .gdbinit file from the CG. When I eliminated the .gdbinit file,
everything ran properly. So apparently, it's a problem with the .gdbinit
file.
Could somebody with more knowledge of what's going on than me look at the
.gdbinit file and tell me what's wrong?
Thanks,
Carl
