Hello! The error is produced by the following (invalid) code

/* oops.c */
unsigned int pData[5];
void f() {
        int i;
        for(i=0; i<5; i++) {
                pData[i] = (float) i;
        }
}

$ gcc -O3 -Wall -Wextra -o oops.o -c oops.c
oops.c: In function ‘f’:
oops.c:6:12: internal compiler error: in expand_fix, at optabs.c:5358
   pData[i] = (float) i;

No warnings are given. I'm on Linux x64, gcc version is 4.9.2, but according to
the godbolt.org all the versions from 4.8 up to 5.1.0 are also affected.
