+++ This bug was initially created as a clone of Bug #1972783 +++ The rebase introduced a regression in debug packages, caught by RPMDiff. The reason is that CFLAGS are not correctly handled for some binaries. The fix is quite trivial, correctly passing down the configure-time CFLAGS to all binaries. https://rpmdiff.engineering.redhat.com/run/498040/
Thank you Marc-Andre! Following are my test results. Any mistakes please correct me. Thanks!
