Title:
[SRU] Please enable frame-pointer on Noble
Status in nspr package in Ubuntu:
Fix Released
Status in nspr source package in Noble:
Incomplete
Bug description:
[ 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

The nspr package comes with a build time test-suite that should ensure
some level of functionality from the re-built library.
override_dh_auto_test:
ifeq ($(filter nocheck,$(DEB_BUILD_OPTIONS)),)
$(MAKE) -C nspr/pr/tests
$(MAKE) -C nspr/lib/tests
# Skip gethost because it needs DNS, and thus networking.
# Skip fdcach, peek and vercheck because they fail.
# Skip socket because it freezes.
# Skip getproto because it fails on some buildds.
# Skip nblayer because it freezes on armel.
cd nspr/pr/tests && grep -v
'^\(fdcach\|gethost\|getproto\|nblayer\|peek\|socket\|vercheck\)$$'
./runtests.sh | sh - $(CURDIR)/nspr/dist
cd nspr/lib/tests &&
LD_LIBRARY_PATH=$(CURDIR)/nspr/dist/bin$(addprefix
:,$(LD_LIBRARY_PATH)) ./base64t
cd nspr/lib/tests &&
LD_LIBRARY_PATH=$(CURDIR)/nspr/dist/bin$(addprefix
:,$(LD_LIBRARY_PATH)) ./string
endif
[ Where problems could occur ]
No source changes are made. 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.
