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.
