build of wxmacmolplt-7.6.2-1.fc24 fails because g++ fails with an internal error, see http://s390.koji.fedoraproject.org/koji/taskinfo?taskID=2149556 for full logs


command to reproduce
g++ -O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -march=z9-109 -mtune=z10 -c -o MEP.o MEP.i

...
MEP.cpp: In member function ‘float Frame::CalculateMEP(float, float, float, BasisSet*, AODensity*, GaussHermiteData*, float*, float*)’:
MEP.cpp:1089:1: internal compiler error: in extract_ops_from_tree, at gimple-expr.h:158
...

with -O1 the error goes away
