Thanks, is this going to be fixed by
https://koji.fedoraproject.org/koji/buildinfo?buildID=1671837 ?

It doesn't look like this fix is mentioned in the %changelog.

Right, I think the patch hasn't yet been approved.  But hopefully it will be soon.  A workaround is to turn off -fanalyzer.

The patch isn't in upstream git yet; looks like I need to respond to comments from Honza on the upstream mailing list

This bug appears to have been reported against 'rawhide' during the Fedora 34 development cycle.
Changing version to 34.

This message is a reminder that Fedora Linux 34 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 34 on 2022-06-07.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '34'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 34 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Fedora Linux 34 entered end-of-life (EOL) status on 2022-06-07.

Fedora Linux 34 is no longer maintained, which means that it
will not receive any further security or bug fix updates. As a result we
are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release.

Thank you for reporting this bug and we are sorry it could not be fixed.
