Subject: [OMPI devel] Invalid free (btl_openib_endpoint.c, 448) in v1.5
From: Mike Dubman (mike.ompi_at_[hidden])
Date: 2011-12-12 12:46:08


Hi guys,

The latest v1.5 from trunk, compiled in debug mode yields following error
with openib.
The quick blame leads to the following commit:

r25616 | bosilca | 2011-12-10 00:18:16 +0200 (Sat, 10 Dec 2011) | 4 lines
Fixes #2930: CMR: memcpy() w/overlapping addresses in
btl_openib_connect_oob.c
Patch attached to the ticket.
