Bug ID: 81220
Summary: [8 regression] ICE during gcc build after r249643
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: seurer at gcc dot gnu.org
Target Milestone: ---
This was on a powerpc64 LE system. I tried this on powerpc64 BE and did not
see the same issue nor when I tried on x86. r249642 works fine.
It occurs when the just built compiler is being used to build some of the
libraries:
make
