Range check error (when turning range checking on) [MULTIPART/FORM-DATA]

Hello!

I have turned range-checking on

At 31105 (rtcInfo v9.22) in TRtcHttpValues.PrepareValues when "right" is going to be read from a file (the payload was large enough to have been written to a file by RTC) i get range check error when the payload is MULTIPART/FORM-DATA... and the string that the browser sent in this request request looked like this:

Code:

------WebKitFormBoundaryfB4CYPVuAwXZpY0q
Content-Disposition: form-data; name="versionComment"


------WebKitFormBoundaryfB4CYPVuAwXZpY0q

The requester indended the "versionComment" field to be blank.

So when we get down to line 31105

Code:

if right='' then
   begin
   StatusLine:=Read_File(ftemp,at,MyPos-at);

MyPos-at = 0 and i think that is what's triggering the exception in ReadFile (via Read_File and Read_FileEx).

1. Did the requester divert from some RFC? There's a lot of JS on the other side so might be possible. I have read some but cannot find the above chunk to be wrong.
2. Should i turn range-checking off? I'd rather like it on as i have found some small thingies in my code when on.
3. Could it be a bug?

TIA,
