Subject: [Bug c++/45265] GCC has an intermittent bug when computing the address of function parameters
Date: Thu, 12 Aug 2010 16:11:00 -0000	[thread overview]
Message-ID: <20100812161123.16057.qmail@sourceware.org> (raw)
In-Reply-To: <bug-45265-19547@http.gcc.gnu.org/bugzilla/>



------- Comment #14 from jakub at gcc dot gnu dot org  2010-08-12 16:11 -------
I never claimed p1 and p2 have different types.  They have the same type.
But the standard paragraph I mentioned says:
"When two pointers are subtracted, both shall point to elements of the same
array object, or one past the last element of the array object"
That is not the case in your testcase, strp and i are different objects.
