It looks like the "%x-extension" string is being passed to a function
like printf (perhaps you use sprintf() instead of strcpy?) - the %x is
then seen as a format specifier for a hexadecimal value, and the next
function argument (or whatever's on the stack if no argument is given)
is used to provide that value (here, you get 0x42ac10 and 0x0).

In general, it's bad practice to have code like

  printf (my_variable);

when my_variable is not known to be a valid printf format string; in
such cases,

  printf ("%s", my_variable);

should be used instead (same goes for sprintf and the other variants).
