mIRC 6.16 only, the processing of raw 338 appears to have broken. If I run the code below, which basically displays a raw numeric and its message:

Code:
raw *:*:{
  /echo -a --
  /echo -a Raw $numeric - $rawmsg
}


It outputs the following when I /whois someone on mIRC 6.16 (I've bolded the line that should have a -- followed by a "Raw 338 - <raw message>" line before it)

Whereas mIRC 6.14 shows the following (using the same code; again, the raw 338 line (missing from 6.16) is italicised, the other line has been bolded)
