Hey, i am not sure if this is an error on my side, but for the union exercise i recieve this error in the traces:

my code is:

`#include <unistd.h>

void searchforletters(char *str1, char *str2, int *str1l, int *str2l)
{
	int i;
	int wrote[127] = {0};
	i = 0;
	while (str1[i])
		{
			str1l[str1[i]]++;
			i++;
		}
	i = 0;
	while (str2[i])
		{
		str2l[str2[i]]++;
		i++;
		}
	i = 0;
	while (str1[i])
	{
		if ((str1l[str1[i]] >= 1 || str2l[str1[i]] >= 1) && wrote[str1[i]] == 0)
		{
			write(1, &str1[i],1);
			wrote[str1[i]]++;
		}
		i++;
	}
	i = 0;
		while (str2[i])
	{
		if ((str1l[str2[i]] >= 1 || str2l[str2[i]] >= 1) && wrote[str2[i]] == 0)
		{
			write(1, &str2[i],1);
			wrote[str2[i]]++;
		}
		i++;
	}
	write(1, "\n", 1);

}

int main(int argc,char** argv)
{
	int str1l[127] = {0};
	int str2l[127] = {0};
	if (argc != 3)
			write(1, "\n", 1);
	if (argc == 3)
		searchforletters(argv[1], argv[2], str1l, str2l);
	return (0);
}
