The cal problem is due to dwz: Changing .debug file CRC not updating it in the main file referencing it.

Comment 3 Jan Kratochvil 2013-07-11 11:24:35 EDT
This bug is about /usr/lib/rpm/sepdebugcrcfix .

The missing top level symlinks is Bug 974130 which is also fixed now.

So it is best to test them now together and any /usr/lib/debug/**.debug file should load fine, even with deleted /usr/lib/debug/.build-id/ .

The correct loading is for example:
Reading symbols from /usr/bin/cal...Reading symbols from /usr/lib/debug/usr/bin/cal.debug...done.

I see I messed up a bit Comment 0 of this Bug.
