Bug ID: 104859
Summary: [12 regression] liibg++ fails during bootstrap
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libgcc
Assignee: unassigned at gcc dot gnu.org
Reporter: seurer at gcc dot gnu.org
Target Milestone: ---
Seen with g:bded0d549fdfdc1328b2c0189dc5f8593b4cbe42 r12-7566-gbded0d549fdfdc
but that is probably not the source. I am still bisecting this but as it is
breaking the build I thought I should open it right away.
