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:

https://koji.fedoraproject.org/koji/buildinfo?buildID=1433152

Version-Release number of selected component (if applicable):

gcc-10.0.1-0.6.fc32
gcc-10.0.1-0.7.fc32

How reproducible:

Always

Steps to Reproduce:
1. Rebuild HepMC3 in rawhide

Actual results:

Failure due to internal compiler error.

Expected results:

Successful build

Additional info:

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.
