This is a report from an interceptor, it is not affected by blacklist,
unfortunately.
You could try MSAN_OPTIONS=intercept_strlen=0, but it is likely that
something else will pop up instead.
Try figuring out what is the actual reason for the report, i.e. what
code is supposed to initialize this mem
For MSan, you'll need MSAN_SYMBOLIZER_PATH. Or just add to PATH, it
would work for all sanitizers.

It works in general.

I think so. What probably happens here is MSan confuses the configure
script into thinking that openpty is available without -lutil, but
what's actually available is just a stub that tries calling the real
openpty and fails, unless libutil is linked.

Yes. Effectively you need two environments - one with
msan-instrumented libraries, and one without. Compilation should
happen in the latter (unless you want to instrument the compiler which
is not very productive), and resulting binaries should be run in the
former.

This is caused by missing -lutil.
