In there is "a.sh", a shell script which calls gcc-9 (fails with both debian gcc-9.3.0-11 or gcc-9.3.0-12). and "a.iii", the preprocessed source. When starting a.sh, in the emulation gcc crashes with segfault. On real hardware gcc succeeds to compile the source. In a hppa-user chroot running "apt update && apt install gcc-9" should be sufficient to get the needed reproducer environment.
