Subject: [OMPI devel] "pml_ob1_sendreq.c:188 FATAL" errors
From: Jeff Squyres (jsquyres) (jsquyres_at_[hidden])

I'm seeing a LOT of these on errors on the trunk:

    pml_ob1_sendreq.c:188 FATAL

The job then hangs. I see this starting at np=6 across 2 nodes, using only the TCP and SM BTLs. This is not happening on v1.6 or v1.7. Line 188 in pml_ob1_sendreq.c is when someone calls mca_pml_ob1_match_completion_free() with a non-OMPI_SUCCESS status.

*** Is anyone else seeing this?

My configure is very straightforward:

    ./configure --prefix=/home/jsquyres/bogus --disable-dlopen --disable-vt

I notice that this is only happening in optimized builds; it is not happening when I do a normal developer / debug build.
