Looks like  Issue 668102 , which was closed without a specific fix?

We keep getting fuzzer bugs in TetrahedralInterpFloat.

I'm unable to reproduce this under MSAN but this seems to be a duplicate of  issue 752725  because I get the same problem trying with ASAN. Let's wait until that issue is fixed to see if this really needs extra attention.
