I think this is caused by the math module somewhere.
Can you provide an IL file that triggers the bug?
math::hypotf64
seems to be causing it. IL source: https://paste.sr.ht/~yerinalexey/884434fae1a12db5917ca591343ae2df5dcb22c1
This should be fixed in the latest QBE version: https://c9x.me/git/qbe.git/commit/?id=1162359a198ab6a18a734cb9f7955d0b28e342b6
