Can anyone explain why the following simple program crashes after the TEXT* objects' first strings are printed for the first time?

Code:
#include <acknex.h>
#include <default.c>

TEXT** makeTexts() {
	TEXT* array[2];
	array[0] = txt_create(10, 1);
	array[1] = txt_create(10, 1);
	
	int i;
	for(i=0; i<10; i++){
		str_cpy((array[0].pstring)[i], "Text1");
		str_cpy((array[1].pstring)[i], "Text2");
	}
	
	return array;
}

function printMessages(TEXT** array){
	printf("%s", _chr((array[0].pstring)[0]));
	printf("%s", _chr((array[1].pstring)[0]));
}

function main() {
	TEXT** array = makeTexts();
	while(1){
		printMessages(array);
		wait(1);
	}
}


The code works fine when it is outside the while loop; the code works until a wait(1) is encountered.
