Package: libc6 Version: 2.34-8 Severity: important Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate *** * What led up to the situation? I upgraded libc6 to latest released 2.35-1 * What exactly did you do (or not do) that was effective (or ineffective)? After upgrade noticed autoreconf --version was failing with **stack smashing detected** message. But in general looks like triggered by expr command. From the coredumpctl got following Message: Process 85280 (expr) of user 1000 dumped core.

Also post this I downgraded libc6 to 2.34-8 from snapshots and no more crash is detected. If anything more is needed do let me know.
