I thought that was from a core dump?

If that was from a running Emacs, then why don't I see what fatal
signal crashed Emacs?  It is the first thing GDB announces when a
debugged program crashes.  If you elided that, please post that part,
it's important.

So where do they come from?  Do you see them in src/Makefile?

Does this mean liblw.a was created in the source directory, not in the
build directory?
