After submission of poppr version 1.1.0 to CRAN, a notification was sent from Dr. Ripley notifying me of an error in UBSAN while running tests:

Analytical value tests : poppr_distance.c:664:5: runtime error: index 1 out of bounds for type 'int [zerocatch[miss_ind]]'

This error stems from illegal memory allocation. I will sanitize the code and post a patch.

potentially fixed in edd6aaa. Will close issue once confirmed from CRAN.

This is not closed yet as it brings up a new error with Address Sanitizer. I have potentially found the bug and fixed it in c9683db.

As this new issue stems from a fix in this current issue, I will not close this until I get confirmation from CRAN.

Looks like an issue with global versus local variable call?

Thanks,
Nik

No. I believe the issue stems from memory not being freed unless a condition is met. Instead of allocating that memory outside of the condition, I am now allocating it inside. I will see if @JonahBrooks can help me make sure that this fixes the issue with ASan

Forgot to include output of ASan:
