Thanks for the replies!

I assumed that this statement was kinda true because if you write something like this:
#include "monocypher.h"

void main()
{
uint8_t hash[64];
const uint8_t message[] = "hello, world";

crypto_blake2b(hash, message, 12);
}

void _start()
{
main();
}

Compile it with the '-nostdlib' flag, as stated by Tom Schwindl, and then run gdb, everything *seems* fine.
Sincerely,
luiz
