RE: Problem with releases since -37


OK - I tried a few more experiments.  I started to experiment outside of my
scripts and got down to:
	XWin -multiwindow &
I ran an xterm on the Linux host using ssh
I ran ddd.
Xwin claimed to dump core (though I could not find a core)

[1]+  Segmentation fault      (core dumped) XWin -multiwindow
xterm:  fatal IO error 32 (Broken pipe) or KillClient on X server
"localhost:10.0"

There was a stackdump file around that had the following:
	Exception: STATUS_ACCESS_VIOLATION at eip=61040870
	eax=00000000 ebx=00003030 ecx=10376698 edx=00000000 esi=103766A0

Though I cannot confirm 100% that ddd did not somehow break the pipe, I can
say that it still works on -37.

I took a quick look at /tmp/XWin.log and did not find anything that looked
like it would be of any help, but I have attached it to this message just in
case it is.
