Hi Glen,
The error is obviously some bug in the internal bookkeeping of DMTCP. The
logs from the coordinator don't indicate much. Could you retry your test
after applying the following patch and configuring and building DMTCP with
`--enable-debug`? The logs from dmtcp_launch could help us identify the bug.

Subject: Re: [Dmtcp-forum] DMTCP + SAS
Hi. Just wanted to ping the list again to see if someone has any idea how to
work around this issue?
Best,

Hi,
I'm trying to run SAS with DMTCP and I get the following error message
immediately on startup and then SAS crashes:
$ dmtcp_launch sas
[40000] ERROR at sysvipcwrappers.cpp:181 in semtimedop; REASON='JASSERT(realId
!= -1) failed'
sas (40000): Terminating...
I'm not really sure what to make of the error message and my Google searches
haven't turned up much in terms of useful information. Any ideas would be
greatly appreciated.
The output of the dmtcp_coordinator is much more verbose:
