@Javagedes, is the PR ready for review now?

@Javagedes, is the PR ready for review now?

Yes

[os-d]

This doesn’t actually fix the reported error; did that not repro or are we not building the lib in CI?

[makubacki]

@Javagedes, this commit message has a typo that makes it difficult to read:

Any if the error handling conditions that cause a
goto Done will call if (Blt != NULL) even
though Blt may not have been initialized. This
commit sets Blt to null at the beggining of the
function to resolve this.

If you could, please fix that before merging.

[makubacki]

If you could, please fix that before merging.

Since @Javagedes is unavailable at the moment, I made that update. Given the pipeline files look reasonable and it would be beneficial to start getting coverage, I am merging the PR now.
