I get

t.c: In function 'foo':
t.c:3:7: error: impossible constraint in 'asm'
       asm (".asciz \"%0\""
       ^

with all versions I try.

I'm using the version of 4.7 packaged in Debian unstable.  It apparently
contains everything up until June 12 in the 4.7 branch, plus a few other
patches.

Oops sorry.  The source package is 4.7.0-13, but I'm still actually using the
binaries from 4.7.0-11, which was released before May 30.
