reduced testcase

This testcase needs more flags to reproduce though:

$ gcc -O2 -fno-tree-ch -fno-tree-fre testcase.c 
testcase.c: In function 'foo':
testcase.c:2:1: error: type mismatch in pointer plus expression
int * restrict

int *

long unsigned int

pretmp.2_13 = p_3 + pretmp.1_12;

testcase.c:2:1: internal compiler error: verify_gimple failed
