Confirmed. I am not sure if this fits Wconversion but it is something subtle
that would be nice to detect.
The testcase should be:
#include <stdio.h>
unsigned val1 = 0x10000000, val2 = 0x100;
int main(int argc, char **argv)
{
unsigned long long val3 = val1 * val2;
printf ("val1 = 0x%X, val2 = 0x%X, val3 = 0x%llX, val1*val2 = 0x%llX\n",
val1, val2, val3, ((unsigned long long)val1)*val2);
}
