GNU Compiler Collection 93597 0 P1 REOPENED [9 Regression] ICE in get_fns since r10-6219 2020-04-05 22:29:27 UTC

Description Mattias Ellert 2020-04-05 21:57:29 UTC 
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
Comment 1 Mattias Ellert 2020-04-05 22:24:53 UTC 
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,
Comment 2 Marek Polacek 2020-04-06 00:42:02 UTC 
Fixed upstream on the 9 branch.
