Comment 1 Nick Clifton 2023-02-07 12:39:34 UTC
This bug only affects binutils versions that have been configured to support the Mach-O file format.  This is not the case on binutils builds for Fedora or RHEL-9 and only affects the binutils builds for the s390x target on RHEL 8/7/6.  See BZ 2167467 for more details on why bugs in Mach-O support is restricted to these releases.

Comment 5 Siddhesh Poyarekar 2023-03-01 17:35:29 UTC
This does not affect gdb in RHEL or Fedora; gdb does not have or build the affected code.
