It is very simple to reproduce this bug. Here is the steps I do
1, download the GCC 4.8.2 from MinGW-w64 site, I'm using

It turned out to be a problem with debugging information.
Some files in libjs_static.a are build with -g, even when
Firefox is configured with --disable-debug

Looking at the assembly, you probably want:
--cut here--
int test (int a, int b, int c)
{
unsigned r = a + b;
if (r (unsigned) a)
return 1;
else if (r c)
return 1;

Explicit cast is not needed here, the compiler will do it for you.

But it would warn about it with -Wsign-compare. You want unsigned r =
(unsigned) a + b; or similar to avoid undefined behavior if there is a
possibility of signed integer overflow.
