Bug ID: 111812
Summary: [14 regression] Can't build with gcc 4.8.5
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: seurer at gcc dot gnu.org
Target Milestone: ---
g:73cd319b72ca45a537688cc8cc5751d86a00a0e9, r14-4306-g73cd319b72ca45
We have one older system that still has gcc 4.8.5 as the distro compiler.
seurer@granola:~/gcc/git/build/gcc-test$ g++ -v
gcc version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC)
If gcc 4.8.5 is no longer the minimum requirement that's fine by me as I can
just build a later version to use.
