You are right, I verified with:

gcc version 9.0.0 20190122 (experimental) (GCC)
COLLECT_GCC_OPTIONS='-v' '-save-temps' '-O3'  '-o' 'test.cpp.o'
'-shared-libgcc' '-march=z13' '-mno-htm' '-mzarch' '-m64'
 gcc/bin/../libexec/gcc/s390x-ibm-linux-gnu/9.0.0/cc1plus -E -quiet -v
-imultiarch s390x-linux-gnu -iprefix
gcc/bin/../lib/gcc/s390x-ibm-linux-gnu/9.0.0/ -D_GNU_SOURCE test.cpp -march=z13
-mno-htm -mzarch -m64 -O3 -fpch-preprocess -o test.ii

and it worked out fine. Sorry for the trouble, thanks for your help!

Preprocessed file and minimal cpp example

This archive contains the preprocessed *.ii file, a .cpp and .hpp file. I was
unable to reduce the file size of the *.ii file below 1000 KB because I had to
include a boost header. However, the .cpp and .hpp files are combined only 10
LOC.
