--- Comment #3 from Peter Seiderer <ps.report@gmx.net> ---
Tested on raspberrypi_4, bash crashes with:

    $ ./host/bin/arm-buildroot-linux-gnueabihf-gdb build/bash-5.2.15/bash
core.199
    Core was generated by `bash'.
    Program terminated with signal SIGSEGV, Segmentation fault.

But e.g. 'LANG=C bash' runs fine...
