Changing the testcase to
void trace(int p1, int p2, int p3, int p4, char * message)
{ char temp[512];
pr(temp, message);
}
is sufficient to demonstrate that the bug has been fixed in all gcc-4.x
versions.
So the problem was fixed some time between 3.4 and 4.0. Sorry, I don't
know precisely which patch, but you are welcome to trawl back through
the gcc-patches email archives for that time frame if you wish; but
don't expect any patches you find to apply directly to the old
code... :-)
