That's really good news, thank you.

05400 oct is 0xb00 hex. As a wait(2) compatible exit code, it would
mean a normal exit, not signal-induced, with an exit value of 11. Which
is kind of suspicious, since 11 is also the signal number of a SEGV. Of
course, not every SEGV must be related to the problem at hand, but
still...
Does emacs have a signal handler which handles SEGVs? If so, you might
consider to set a breakpoint on this signal handler in GDB.
