We have seen printf causing access violations if the resultant
string is > 512, no matter what.  It's not the format string that's
causing the problem, but the size of all the data that will be
generated.  Sounds like an array of 512 on the stack that trashes
your return values.  We were printing out long lines of 1's and
were seeing access violations for address 31313131 (hex 31 is
ascii '1').  We run C 2.3 and VMS 4.4.
