Bug ID: 117300
Summary: guality tests always fail on Fedora 41
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: hjl.tools at gmail dot com
Target Milestone: ---
On Fedora 41, gdb defaults to use debuginfod. I got
Spawning: gdb -nx -nw -quiet -batch -x pr36728-2.gdb ./pr36728-2.exe
spawn gdb -nx -nw -quiet -batch -x pr36728-2.gdb ./pr36728-2.exe
Breakpoint 1 at 0x4004ba: file

line 18.
This GDB supports auto-downloading debuginfo from the following URLs:
<https://debuginfod.fedoraproject.org/>
Enable debuginfod for this session? (y or [n]) [answered N; input not from
terminal]
Debuginfod has been disabled.
To make this setting permanent, add 'set debuginfod enabled off' to .gdbinit.

I added 'set debuginfod enabled off' to ~/.gdbinit. Since -nx option ignores
~/.gdbinit, guality tests always fail.
