--- Comment #6 from Martin Sebor ---
Sorry, I didn't give enough details in the report. As discussed in the
gcc-patches thread referenced in comment #0, the bug is latent on current
trunk. It only manifests itself when the fix for bug 86532

--- Comment #5 from U.Mutlu ---
I have to correct myself in #2 and #3.
The code is correct, and should return n=6.

--- Comment #4 from U.Mutlu ---
gcc version 4.9.2 (Debian 4.9.2-10+deb8u1) gives the same result as v9:
p=123456 n=6

--- Comment #3 from U.Mutlu ---
I just tested it with v9:
#include
static const char a[3][8] = { "1234", "12345", "123456" };
int main ()
{
volatile int i = 1;
const char* p = *([1] + i);
int n = __builtin_strlen (p);
