<pre>consider:
inline int func(bool f) {
if (f) {
static int i;
i++;
return i;
}
static int i;
i++;
return i;
}
int call(bool f) {
return func(f);
}
MSVC does something unworkable, both 'i' declarations have the same external
name.
They assign them both:
?i@?4??func@@YAH_N@Z@4HA
I believe we can do the following instead:
first 'i' gets: ?i@?4??func@@YAH_N@Z@4HA
second 'i' gets: ?i@?0?4??func@@YAH_N@Z@4HA
This has the advantage of demangling to something that makes sense while _also_
ensuring that we don't collide with anything else.</pre>
