How do you think that overflow check is done inside std::string?

What do you mean with "more explicit check for overflow"?
Assuming you know the variables are 32-bit unsigned, I suppose you could do
if (pathlen < 0xFFFFFFFF-filelen)
{
pathlen += filelen;
}
else
{
return 0;
}
and then repeat, but honestly I don't see the benefit of it compared to
the above (as a first you are introducing a dependency on the specific
integer size).
Or you can cast to a wider type, but then you are not solving the
problem, you are only moving it forward, and still I wouldn't see the
benefit.
Besides, this is about /integer/ overflow check, so it could apply to
more computations other than memory size.
