Description of problem: After the update to gcc 9.3.1 in Fedora 31, the HepMC3 package started fail to build due to an internal compiler error: https://koschei.fedoraproject.org/package/HepMC3?collection=f31 I have reproduced the failure reported by Koschei using a local mock build. Version-Release number of selected component (if applicable): gcc-c++-9.3.1-1.fc31 How reproducible: Found by Koschei, reproducible in local mock. Steps to Reproduce: 1. Rebuild HepMC3-3.2.1-1 in Fedora 31 using gcc 9.3.1-1 Actual results: ICE - failed build Expected results: Successful build Additional info: This is a regression. The package could be built using gcc 9.2.1-1.fc31
The same error happens using gcc-c++-9.3.1-1.fc30 in a Fedora 30 mock build - this was not tested by Koschei yet,
Fixed upstream on the 9 branch.
