[Bug c++/35099] New: [OpenMP] ICE in remove_unreachable_regions with -O -fopenmp

[t-gcc-bugzilla at snowelm dot com]

g++ on the trunk (revision 132140) produces ICE when compiling the attached
test1.ii.  I tried to reduce the code but I couldn't.

$ g++-4.3 -E test.cpp -o test1.ii
$ g++-4.3 -O -fopenmp test1.ii
hoge.cpp: In function 'void
_Z15test_learnervecP15EnvironmentBaseRSt6vectorIP11LearnerBaseSaIS3_EEiSs.omp_fn.0(void*)':
hoge.cpp:85: internal compiler error: in remove_unreachable_regions, at
except.c:693
