Solving segmentation fault problem in gdb

[Carl D. Sorensen]

I'm trying to get the CG instructions for using gdb up-to-date.  And I'm
trying to debug a problem with the new autobeam stuff I'm working on.

So I checked out a fresh master.

Then I did

./configure --enable-debugging
make

gdb lilypond

inside of gdb, I did

(gdb) run testfiles/autobeam-test.ly
Starting program: /Users/Carl/lilypond-working/out/bin/lilypond
testfiles/autobeam-test.ly
Segmentation fault


But when I run from the command line, everything works correctly.

Any thoughts on how to debug this segmentation fault in gdb?

Thanks,
