in reply to Inline::C not behaving as expected

Though you are using strncpy(), your string is not null-terminated. (update: to quote from the docs for strncpy on my machine "if there is no null byte among the first n bytes of src, the result will not be null-terminated.") To fix this probably you can do one of the following:

  • Add a date[8] = '\0'; line.
  • Use newSVpvn(date,8) to create a string of a specific length.

I would note that your current use of newSVpvf() should be replaced with newSVpv(date,0) or similar, to prevent odd behavior and/or major security flaws from popping up if your data contains %s. (Or, at least, to prevent you from getting in to the habit of coding that way for when it would matter.)
