Bug 82012 filed (as noted there, I don't know if the problem is in the
compiler or libitm). I can confirm the same failure appears building the
preprocessed source with a GCC 7 branch compiler with -flto added to the
options, rebuilding trunk r251332 to check with that.
Options used with GCC 7 branch to get the same error:
s390x-glibc-linux-gnu-g++ -S -o /dev/null -ftls-model=initial-exec -mzarch
-mhtm -std=gnu++0x -funwind-tables -fno-exceptions -fno-rtti
-fabi-version=4 -g -O2 -fPIC beginend.ii -flto
