We fixed this issue a while back.<br>

You can apply the following patch<br>

Mark,<br>
<br>
You seem to have somewhere in the source a call to Allgather
that<br>
improperly uses the same buffer as the first and 4th actual
argument.<br>
<br>
Try to locate this call. I assume it is in user-provided
code; if it<br>
was in a part of the FLASH code that gets exercised under
normal<br>
circumstances, we should have already run into it and fixed
it.<br>
