Does this still happen with newer versions of GCC? I can't reproduce with gcc
7, but I'm assuming that's due to target differences; I get different messages
depending on 32-bit or 64-bit, but neither of them are an ICE:
$ gcc -c -m32 15896.c
15896.c: In function 'f':
15896.c:4:3: error: inconsistent operand constraints in an 'asm'
asm("%0"::"a"(cu32));
^~~
$ gcc -c -m64 15896.c
15896.c:4:Junk character 37 (%).
15896.c:4:Rest of line ignored. 1st junk character valued 114 (r).
