Subject: [OMPI users] OpenMPI 1.3.2 with PathScale 3.2
From: Joshua Bernstein (jbernstein_at_[hidden])

Greetings All,

        I'm trying to build OpenMPI 1.3.2 with the Pathscale compiler, version 3.2. A
bit of the way through the build the compiler dies with what it things is a bad
optimization. Has anybody else seen this, or know a work around for it? I'm
going to take it up with Pathscale of course, but I thought I'd throw it out here:

/opt/pathscale/bin/pathCC -DHAVE_CONFIG_H -I. -I../.. -I../../extlib/otf/otflib
-I../../extlib/otf/otflib -I../../vtlib/ -I../../vtlib -D_GNU_SOURCE -mp
-DVT_OMP -O3 -DNDEBUG -finline-functions -pthread -MT vtfilter-vt_tracefilter.o
-MD -MP -MF .deps/vtfilter-vt_tracefilter.Tpo -c -o vtfilter-vt_tracefilter.o
`test -f '' || echo './'`
Signal: Segmentation fault in Global Optimization -- Dead Store Elimination phase.
Error: Signal Segmentation fault in phase Global Optimization -- Dead Store
Elimination -- processing aborted
*** Internal stack backtrace:
