Title:
  [SRU] xfsprogs missing frame pointer

Status in xfsprogs package in Ubuntu:
  Confirmed
Status in xfsprogs source package in Noble:
  New
Status in xfsprogs source package in Oracular:
  Fix Released

Bug description:
  xfsprogs missing frame pointer despite the build flags already contain
  compiler flags to enable frame pointers.

  [ Impact ]

  In order to help developers with profiling, Ubuntu enabled frame-
  pointers for packages in the main archive.

  https://ubuntu.com/blog/ubuntu-performance-engineering-with-frame-
  pointers-by-default

  The `Affects` packages were missed due to the packaging issues. These
  have been fixed on Oracular and can now be ported to Noble.

  [ Test Plan ]

  Look at the DW_AT_producer in the associated debug ELF file for flags.
  -fno-omit-frame-pointer should be present after the fix.

  The following scripts can be used as a reference

  https://gist.github.com/julian-klode/95818246eaef0ac6a54588f7f368e25c

  You can also check the build logs for build flags like `-fno-omit-
  frame-pointer`.

  [ Where problems could occur ]

  * A distribution-specific patch was applied to fix the build with security hardening flags enabled.
  * The packaging fixes have enabled other security hardening flags. This could have unintended effects.

  [ Other Info ]

  changes in dpkg have been made to make sure frame-pointers are not
  enabled on s390x and ppc64el.
