Bug ID: 81424
Summary: gnat bugbox on i386
Product: gcc
Version: 7.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
Assignee: unassigned at gcc dot gnu.org
Reporter: pavel at zhukoff dot net
Target Milestone: ---
During compilcation of gprbuild or gnatcoll on i686 in Fedora compiler exits
with unrecoverable error [1].
Reproducer https://landgraf.fedorapeople.org/gccbug.tgz. Compilation options
are in command.sh file inside.
Fedora bugreport: https://bugzilla.redhat.com/show_bug.cgi?id=1444614
It affects entire stack of Ada program in Fedora as all of them are blocked by
this.
As gcc<7 works fine and both gprbuild 2016 and 2017 from AdaCore cannot be
compiled with gcc>=7 I suspect the problem is in gcc itself not gprbuild.
