<div>
<pre>The following example prints 0 if both -fsanitize=address and /MD are passed as
arguments:
#include <cstdlib>
#include <iostream>
int main ()
{
char *eptr;
auto value = std::strtol ("99999999999999999999999999999999999999999", &eptr,
10);
std::cout << errno << '\n';
}
The correct result is printing 34 (ERANGE)
I have checked that the rest of this funciton family (stdtoul, strtoll,
strtoull, strtof, strtod, strtold) are not affected which makes this problem
strangely specific to strtol.</pre>
