It does produce a warning about dreferencing a type-punned pointer. I tried to compile the snipped with both -fstrict-aliasing and -fno-strict-aliasing and it doesn't produce a difference in the code. Not on the i486 gcc4.5 nor on the gcc4.4 in fedora. Busybox uses this in some places and it did work in the past, so it would be really nice, if this could get fixed. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44060
