[github-actions]

Potential segfault in localtime_r invocations

Details
Package	chrono
Version	0.4.19
URL	chronotope/chrono#499
Date	2020-11-10

Impact

Unix-like operating systems may segfault due to dereferencing a dangling pointer in specific circumstances. This requires an environment variable to be set in a different thread than the affected functions. This may occur without the user's knowledge, notably in a third-party library.

Workarounds

No workarounds are known.
