The library is not UBSan friendly.

This issue has been found while we tried to integrate the library to ClickHouse.
ClickHouse is tested with ASan, MSan, TSan and UBSan with several kinds of continuous fuzzing.

Do you have a minimum test case that fails? I was unable to reproduce this when running locally.

[AlexanderSaydakov]

@jmalkin It may or may not fail depending on platform and compiler. UBSan catches undefined behavior that potentially might fail somewhere.

@alexey-milovidov Would you like to submit a pull request or would you like us to apply your suggested patch? Thank you.

[jmalkin]

@AlexanderSaydakov yes, I added flags to compile and link with UBSan and ASan using -fcoverage options and found nothing. I may well be doing something incorrectly, of course.

It's ok if you commit this patch under your name. My collegue will share an example, but only tomorrow.
