I wondered if it really was something special about CRC32CW, so tried changing that for MUL, but got the same fatal error.
Then I wondered if the inline assembler was important at all, so deleted that, but got the same fatal error.
Attached is a smaller test case only in C. If you remove the inline qualifier it compiles OK, so failure to inline seems to be the real issue at hand.
