Description Bernhard Wiedemann 2019-07-12 12:53:09 UTC 
As part of my work on reproducible builds for openSUSE
I found that the addition of -flto variations from CPU count
now causes variations in debug_info sections in .o files
contained in .a archives

Steps to Reproduce:
osc co openSUSE:Factory/ffcall && cd $_
osc build --vm-type=kvm -j1 --debuginfo --keep-pkg=.rpm1
osc build --vm-type=kvm -j2 --debuginfo --keep-pkg=.rpm2
/usr/lib/build/pkg-diff.sh .rpm{1,2}/ffcall-2.1-0.x86_64.rpm

also affects others: ibmtss zlib ...

ffcall is very likely also affected by:

and ibmtss will be affected by the same as well

This is fixed meanwhile.
