Hi,

I tried to collect stdout from a spawned task (genereated with
write(6,*)...) using the command

	call pvmfcatchout(1) 

from the parent. Result: Memory fault whith core dump in pvmfcatchout.
After looking in the pvmfcatchout.m4 source I found out that the
subroutine needs two arguments in order to work, so I modified to

	call pvmfcatchout(1,info)

This is a documentation bug (in ug.ps and in the man page). The
modified call didn't dump core, but it didn't work either. I can't
seem to find the stdout (or stderr) of spawned tasks anywhere.
Am I missing something or is this really a bug?
Configuration: 10 RS6K Workstations with PVM 3.3.0, compiled with xlc
1.2.

I would appreciate any hints.  Klaus-Georg Adams
