I just extracted it from dbus package which I am testing on linux/alpha

Should not be some warning to be generated?
There is a warning if going directly from char * to the union pointer but since

This most likely can be reproduced on ia64 too and other targets where

The tree which we produce looks like:
bb 0:
if (p-c[0] != 0) goto L0; else goto L2;
