I have an unchanged mingw toochain I have beeen using successfully for
months, and I also see a crash during bootstrap.

From my build log for bootstrap of r114374, it crashed while compiling
lisp/cedet/semantic/db-ebrowse.el. Attaching gdb and issuing 'thread
apply all bt' did not obtain a backtrace:

(gdb) The program being debugged exited while in a function called from GDB.
Evaluation of the expression containing the function
(backtrace_top) will be abandoned.

The rest of the build continued to completion. This seems to be
repeatable. Anything I can do to help diagnose it ?
