I have built both 1.4.3rc1 and 1.5rc5 using the 3.2 PathScale compilers.
I did not encounter the problem Larry reported, but there are (at least)
2 differences between my build and Larry's
1) I didn't pass and explicit {C,CXX,F,FC}FLAGS
2) My pathcc install is using the gcc4 toolchain, not gcc3.
I plan a few more builds to narrow down the differences.
Some notes:
To build 1.5rc5 with this compiler I needed a 1-line change
(http://www.open-mpi.org/community/lists/devel/2010/08/8413.php)
My configure args for both 1.4.3rc1 and 1.5rc5:
$ [path_to]/configure \
configure --with-contrib-vt-flags=--with-platform=linux \
CC=pathcc-3.2 CXX=pathCC-3.2 \
F77=pathf90-3.2 FC=pathf90-3.2
Note that the "--with-contrib-vt-flags=--with-platform=linux" is because
the machine is a front-end to a Cray XT and I wanted to build VT for the
front-end, not for the Cray.

Among the tests I conducted but did not report was a successful build

This was a beta release of the 3.3 (never released?) provided to some
customers, and not a general release.
I also note that my PathScale install is using gcc-4, rather than
gcc-3, which I understand contains different bugs.
I will test the "stock" 3.2 with 1.5rc5 and 1.4.3rc1 and report my
findings.

The PathScale 3.2 C++ compiler segment faults for optimization levels
higher than -O1 (-O2 is the default). This is for OpenMPI 1.4.2 — my
first attempt to compile using the PathScale compilers. I could not
find any -WOPT options to eliminate the error. I don't understand
the current state of the PathScale compilers. I think the company
changed hands since we bought the product and the last owner went
bankrupt. I think the name has been resurrected by the people that
wrote the compiler. They use the same name, but I get the impression
that our license is with a company that is gone now, not with them,
so they want us to buy a new license. Anyway, there may be a newer
compiler than 3.2 that does not have this problem.
