I reproduced it locally as well. Extracted preprocessed file as bug.cpp.xz (not
yet reduced).

To crash:

g++ -O3 -Wall -Wextra -Werror -Wfatal-errors -Wno-error=stringop-overflow
-Wshadow -Wcast-qual -Woverloaded-virtual -Wnon-virtual-dtor -mrtm -mwaitpkg
-std=c++11 -c bug.cpp -fPIC -fstack-protector-strong --param ssp-buffer-size=4
-fno-strict-overflow
