Commit 23fff7a17f lies within that range and certainly feels like it could be 
relevant to the above failure:

    linux-user/s390x: Use the guest pointer for the sigreturn stub

    When setting up the pointer for the sigreturn stub in the return
    address register (r14) we currently use the host frame address instead
    of the guest frame address.

    Note: This only caused problems if Qemu has been built with
    --disable-pie (as it is in distros nowadays). Otherwise guest_base
    defaults to 0 hiding the actual problem.

I'll try pushing a test build to Gitlab CI with a revert for that patch on top and 
see if it succeeds for me...


ATB,
