Subject: Bug in atoll strtoll, the output of then differ
Hello !
Doing some work with emscripten with this project
https://github.com/mingodad/CG-SQL-Lua-playground I was getting some
errors with the usage of "atoll" and with this small program to compare
the output of "musl" and "glibc" I found what seems to be a bug in
"atoll" because with "musl" it gives a different output than "strtoll".
=====
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
const char *s = "9223372036854775808";
long long ll = atoll(s);
long long ll2 = strtoll (s, (char **) NULL, 10);
int imax = 0x7fffffff;
printf("%s : %lld : %lld : %d : %d\n", s, ll, ll2, imax, ll <= imax);
return 0;
}
=====
Output from "glibc":
=====
9223372036854775808 : 9223372036854775807 : 9223372036854775807 :
2147483647 : 0
=====
Output from "musl":
=====
9223372036854775808 : -9223372036854775808 : 9223372036854775807 :
2147483647 : 1
=====
Cheers !
