https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64327 --- Comment #9 from Vittorio Zecca --- Sorry for the delay in answering but I was traveling. I cannot reproduce on version 7, while it reproduces on 6.4.0.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64327 --- Comment #7 from Vittorio Zecca --- On 6.1.0 I applied the same patch I suggested on comment 6, this time at line 5187, and the runtime error disappeared.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64327 --- Comment #6 from Vittorio Zecca zeccav at gmail dot com --- I fixed this one by substituting rtlanal.c:4907 if (bitwidth HOST_BITS_PER_WIDE_INT ) with if (bitwidth HOST_BITS_PER_WIDE_INT || !bitwidth)

--- Comment #4 from Vittorio Zecca zeccav at gmail dot com ---
For your convenience I repeat here the reproducer:
/* from gcc file fixopts.c */
/* must be compiled with -O2 */
/*gcc-5.1.0/gcc/rtlanal.c:4911:48: runtime error: shift exponent
4294967295 is too large for 64-bit type 'long unsigned int'*/
/*on source line return nonzero ((unsigned HOST_WIDE_INT) 1
(bitwidth - 1))*/
/* because unsigned int bitwidth is zero and bitwitdth-1 is 4294967295
on my x86-64 */
/* I did double check with:
* bitwidth = GET_MODE_PRECISION (mode);
* gcc_assert(bitwidth);
*/
/* the bug appears compiling fixopts.c crc32.c md5.c and many Fedora
21 kernel files*/
/* 66853 duplicato di 64327 */
int strcmp(const char *s1, const char *s2);
int fixinc_mode; /* must be outside main for bug to appear */
int main (void)
{
const char *pz;
if (strcmp (pz, true) ) fixinc_mode = 0;
}
