Subject:	Sporadic make core dump

--------------ms0E5C9CA5F994E2E07691F2F4
Content-Type: text/plain; charset=us-ascii

I have the sporadic make core dump problem.  The environment is a very heavily recursive makefile setup.  I can't post exact steps
to repro, but perhaps you can repro easily with an attempt to build mozilla.  I notice that if I start make in a CMD window
running bash, leave the window on top, and don't start any other applications during the make run (including screen savers, virus
software, etc.), it runs fine.  However, if I open another application during the make run, or even open a window which was
minimized, it will sometimes crash with the following error message.  I wonder if there is some window change signal being passed
to the application?  I remember in my old SunView days, there was a SIGWINCH which was delivered when windows were raised,
lowered, etc.  It seems similar, but the signal reported is Signal 11 (Seg. fault).

      0 [main] make 202 open_stackdumpfile: Dumping stack trace to make.exe.stackdump
Signal 11

Here is the stackdump file:
