Subject: Re: [OMPI devel] 1.4.4rc2 is up
From: Larry Baker (baker_at_[hidden])

This bug applies to OpenMPI 1.4.x and 1.5.x.

The libtool.m4 in config and opal/libltdl/m4 do not properly determine
the version of the PGI compiler, which then set the wrong compile/link
options. They interpret V11.4 (version no. begins with a 1), for
example, as being a V1 to V5 compiler. There is a missing period in
the pattern, so that only text like 1.x through 5.x matches.

Here's the diff -u from OpenMPI 1.4.3 (same code, same bug):
