_itoa (not all compilers have this - some omit underscore) or sprintf

#include <stdlib.h>
#include <stdio.h>

int main( int argc, char * argv[] )
char s1[256] ;
char s2[256] ;
int i1 = 1 ;
int i2 = 2 ;

sprintf( s1, "%d", i1 ) ;
_itoa i2, s2, 10 ) ; /* 10 = base ten */

return 0 ;


oops typo, I meant:
_itoa( i2, s2, 10 ) ; /* 10 = base ten */

I am compiling in gcc (on unix), and the _itoa seems to be accepted except the demonstration code returns a segmentation fault when executed.
Any ideas?

By the way I am removing the sprintf line!
You'd be more portable keeping the sprintf and removing the _itoa line
