Does anyone know why this is crashing??

[Robert Angelino]

I have this bit of code that works perfectly on a SPARC and crashes
on a VMS (O/S- V5.3-A) system?!

int
init_files(startup_file,...)
	char *startup_file;
{
char buf[256];

#define EOPEN "Unable to open %s file \"%s\"\n"
(void) print_msg(PERROR,"init_files()",
                 sprintf(buf,EOPEN,"startup",startup_file));

	.
	.
	.
	.
	.
	.
}

main()
{
char buf[256];

(void) strcpy(buf,"tc_startup.dat");
(void) init_files(buf,...);

}

It's crashing when it hits the sprintf call in init_files().
I have the following logicals set in the build env
(LNM$PROCESS_TABLE)

  "LNK$LIBRARY" = "SYS$LIBRARY:VAXCCURSE"
  "LNK$LIBRARY_1" = "SYS$LIBRARY:VAXCRTL"


any and all help/suggestions are welcome and will prevent further 
hair lose.

thanks in advance
