           Summary: ice in estimate_node_size_and_time, at
                    ipa-fnsummary.c:2750

gzipped C++ source code

Recent gcc trunk with flags -O2 -fno-guess-branch-probability
and the attached C++ source code does this:

during IPA pass: inline
src/symmetrictraversal.cpp:617:1: internal compiler error: in
