I encountered the same issue and here is Pathscale's response: "C++ OpenMP is not fully supported in the GCC3-based front-end, that your compilation is using. This old front-end is being used probably because you are compiling on a GCC3-based linux distribution. You are seeing this failure due to this incomplete support. A solution is moving to a GCC4-based distribution so that the compiler uses the new GCC4-based front-end with C++ OpenMP support. You can also trying adding -gnu4 option to your compilation on a GCC3-based system, but it is not always guaranteed to work on GCC3-based systems." -Ethan > > On Jan 23, 2009, at 8:53 PM, Alain Miniussi wrote: > >> >> FYI: >> >> I get the following problem when compiling openmpi-1.3 at -O2 and beyond: >> >> [alainm@rossini vtfilter]$pwd >> /misc/nice1/alainm/openmpi-1.3/ompi/contrib/vt/vt/tools/vtfilter >> [alainm@rossini vtfilter]$make CXXFLAGS=-O2 >> pathCC -DHAVE_CONFIG_H -I. -I../.. -I../../extlib/otf/otflib >> -I../../extlib/otf/otflib -I../../vtlib/ -I../../vtlib -D_GNU_SOURCE -mp >> -DVT_OMP -O2 -MT vtfilter-vt_tracefilter.o -MD -MP -MF >> .deps/vtfilter-vt_tracefilter.Tpo -c -o vtfilter-vt_tracefilter.o `test -f >> 'vt_tracefilter.cc' || echo './'`vt_tracefilter.cc >> 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: >> pathCC INTERNAL ERROR: /opt/pathscale/lib/3.2/be died due to signal 4 >> Please report this problem to <supp...@pathscale.com>. >> Problem report saved as /home/alainm/.ekopath-bugs/pathCC_error_15P2Vc.ii >> Please review the above file and, if possible, attach it to your problem >> report. >> make: *** [vtfilter-vt_tracefilter.o] Error 1 >> [alainm@rossini vtfilter]$ >> >> the problem disapear at -O1. >> >> I sent all the relevent informations to pathscale support. >> >> Best regards, >> >> -- >> Alain Miniussi >> Equipe CRIMSON Mesocentre de Calcul SIGAMM >> +33 492 00 30 09 https://crimson.oca.eu >> _______________________________________________ >> users mailing list >> us...@open-mpi.org >> http://www.open-mpi.org/mailman/listinfo.cgi/users > > > -- > Jeff Squyres > Cisco Systems > > _______________________________________________ > users mailing list > us...@open-mpi.org > http://www.open-mpi.org/mailman/listinfo.cgi/users
