This is the second time I've encountered this now.

When compiling Emacs, it crashes at this exact same file. Restarting
compilation or 'make bootsrap' doesn't fix it, but rebooting the
machine does.

Also, this time around I tried to recompile it with CFLAGS="-Og -g3",
and the crash also went away.

Attached are the relevant piece of the compilation output, and the
result of running it though sed+addr2line.

No idea how to catch this crash in gdb, suggestions welcome.

In GNU Emacs 24.3.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.8.6)
