--- Comment #22 from Stefan Schulze Frielinghaus <stefansf at gcc dot gnu.org> --- I started a bootstrap+regtest, too, for targets z900,z10,z13,z16. Each run will take around 5 hours. I will report back once they finished or if some fail on the go. I have attached a preprocessed input which fails if gcc was build for z900 using command line: c++ -std=c++11 -fno-exceptions -O2 -fno-rtti -fno-threadsafe-statics -fvisibility-inlines-hidden -fPIC hb-subset.ii -c -o foo.o In the meantime I will reduce, too.
