[v1.1.36.0] Invalid memory read/write with switch Topic is solved

[RaptorX]

I have been having this error come up very often on v1.1.36.0

1.1.36.00 32bit
5
Critical Error: Invalid memory read/write.

Line#
306: Return,Trim(data, "
")
307: }
310: {
313: Gui,main:Default
314: Gui,Submit,NoHide
316: sci.SetText(false, "")
318: preview := HrefLink.Convert(source ? source : HrefType)
---> 320: Switch preview
321: {
322: Case ERRNONHTML:
323: MsgBox,"The script couldnt access the HTML clipboard on this computer."
324: Return,false
325: Case ERRNONLINKS:
326: MsgBox,"The text selected doesnt contain HTML."
327: Return,false

The program is now unstable and will exit.

I cant reproduce exactly when this would be triggered but is really frequent at the moment.

EDIT:

well, there seem to be a type mismatch between my variable and the switch case value:

The interesting thing is that my function actually returns a variable that contains a number, so im not sure why the preview variable is set as a string.

Same here. I was just copying the code to paste it here, when the error occurred again. It's back to 1.1.35.00, build number "ASAP"!

Code: Select all

clipChanged(type := "") {
 Global
 If !clipFile || clipsProcessing || clipText || !clipStarted
  Return
 ; tip2("clipsB = " clipsB)
 Switch clipsB {
  Case False: Gosub, ClipsInsert ; Clipboard source is not listview, so insert text into listview
  Case True : Gosub, ClipsPaste  ; Clipboard source is listview, so paste the text
 }
 clipsB := False
}

Raptor and Mikey,

Does this also NOT happen with the 32-bit version, as Raptor discovered at my bug report:

Sorry, Joe, I already pulled the plug! I will assume that you are correct, and await the next round. Thanks for your coordination surrounding this issue.

This has the same cause as Switch bug introduced in 1.1.36, fixed by v1.1.36.01.
