Description of problem:
With the update from gcc-10.0.1-0.5.fc32 to gcc-10.0.1-0.6.fc32 the build of HepMC3 started failing with an internal compiler error. This happens for all architectures. The package failed the mass rebuild:
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Rebuild HepMC3 in rawhide
Failure due to internal compiler error.
This is a regression from gcc-10.0.1-0.5.fc32. If I download the RPMs from koji for the gcc-10.0.1-0.5.fc32 and install them in a rawhide mock changeroot, the HepMC3 package can be built in this environment.
I will need a preprocessed source file to look at this ICE; could you perhaps run an x86_64 scratch build with something like
make ... || (tar cf - /tmp/cc*.out | bzip2 -9 | uuencode cc.tar.bz2)

This bug appears to have been reported against 'rawhide' during the Fedora 32 development cycle.
Changing version to 32.
