Bug ID: 115113
Summary: [15 Regression] Ada bootstrap fails for i686-darwin.
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
Assignee: unassigned at gcc dot gnu.org
Reporter: iains at gcc dot gnu.org
CC: dkm at gcc dot gnu.org
Target Milestone: ---
Target: i686-darwin
between - r15-386 and r15-516
not analysed any further yet - but x86_64 bootstrap on the same OS rev appears
unaffected.
several instances of memory constraint errors..
At the moment, it's the stage#2 gnat1 that's failing - so no debug info...
