X-Debbugs-Cc: [email protected]
Control: affects -1 + src:rust-time
User: [email protected]

[ Reason ]
CVE-2026-25727 (stack exhaustion)
[ Impact ]
Vulnerable to denial of service.

Code change is trivial. There is only an inline annotation that had to
be dropped to backport the patch.

[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in oldstable

Team upload.
