If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- noble to verification-done-noble. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-noble. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B.

Therefore, having a (soft/simulated) frame pointer does not improve backtraces at all on Power. However, forcing a frame pointer via the -fno-omit-frame-pointer option negatively affects performance for multiple reasons: extra prologue/epilogue overhead and fewer shrink-wrapping opportunities. Given -fno-omit-frame-pointer does not provide any improvements (backtraces or otherwise) and only reduces performance, -fno-omit-frame-pointers should not be used on Power. SRU: these changes were implemented during the opening of the oracular series. The very same changes are backported to 24.04 LTS. These only affect the ppc64el and s390x architectures, for other architectures it's a no-change upload. We didn't see any fallout for these changes during the development on the oracular series, and therefore don't expect any fallout or regressions in 24.04 LTS either.
