Our MPI folks detected a hang while using Valgrind with our ConnectX cards.
After trying the current master branch in git we solved the problem by applying
this patch from the git tree to v1.0.
Don't use memcpy() to write blueflame sends
Some memcpy() implementations may use move-string-buffer assembly
instructions, which do not guarantee copy order into the blueflame
buffer. This causes problems when writing into a blueflame buffer, so
use our own copy function instead.

While doing this I noticed that the last release tag in the git tree is way
back in Dec 2007. Is there a planned release of libmlx4 soon? What version
is OFED pulling? RedHat is still using 1.0.
Thanks,
Ira
