GNU Compiler Collection 93597 P1 RESOLVED [10 Regression] ICE in get_fns since r10-6219 2020-02-23 05:07:20 UTC

Description Mattias Ellert 2020-02-05 15:23:12 UTC
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):


How reproducible:


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.

Comment 1 Marek Polacek 2020-02-05 15:28:34 UTC
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.
