Description Mamoru TASAKA 2026-06-24 10:05:34 UTC 
On rawhide rebuilding rubygem-atk fails:

https://koschei.fedoraproject.org/package/rubygem-atk?collection=f45
https://koji.fedoraproject.org/koji/taskinfo?taskID=146989377

```
+ cd atk-4.3.6
+ /usr/bin/chmod -Rf a+rX,u+w,g-w,o-w .
+ mv ../atk-4.3.6.gemspec .
mv: cannot stat '../atk-4.3.6.gemspec': No such file or directory
```

Checking buildroot shows there is actually "atk-4.3.6..gemspec" file:

```
<mock-chroot> sh-5.3# ls -1 /builddir/build/BUILD/rubygem-atk-4.3.4-build/
SPECPARTS
atk-4.3.4
atk-4.3.4..gemspec
rpmbuild.env
```

Most likely this is because of the following change:
https://github.com/rpm-software-management/rpm/pull/4113/changes/b8b54f92c65bca7bfdd80c3ecf717d5c48b02e91

rstrlcpy implemention puts the sentinel null character, while std::string(bn, nvlen); copies the string bn with the "length" of nvlen.

rpm-6.0.91-1.fc45.x86_64
rubygem-atk-4.3.6-1.fc45.src

Reproducible: Always

Oops. Thanks for the report, will fix ASAP. 

This is apparently one of the things with zero tests still, which is why such fallout happens.
