------- Comment #20 from howarth at nitro dot med dot uc dot edu 2010-03-09 03:45 ------- The offending optimization for the spectop subroutine at -O2 -fgraphite-identity appears to be -fstrict-overflow. I can compile...
gfortran -fgraphite-identity -O3 -fno-strict-overflow -c spectop.f90 gfortran -O3 -fgraphite-identity air_sans_spectop.f90 spectop.o and the resulting air benchmark runs fine. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42181
