Hi guys.

Today I encountered a problem with AHK_L again. I wanted to convert a script that downloads a file with httpQuery [Unicode version by HotKeyIt] and uses a MD5 check afterwards. The problem is that the MD5 sum function uses the and afterwards to set the format back.
But this command crashes AHK_L (Windows throws an exception that AHK_L does not work anymore, search for problem blabla).
Even though the line will be never executed, like in this example:

There are two things I can do to get around this issue:
1. Remove all lines, which use SetFormat, Integer
2. Don't use a url with binary files, e.g. http://google.com/ works

It would be great, if someone knows how to fix this problem or what the issue might be.

Kindly regards,
nfl

BTW: I am using the latest AHK_L unicode version (1.0.97.1)

The script crashes for me with or without SetFormat. I suspect that it is crashing in Struct_getVar, which relies on undocumented implementation details to do things that AutoHotkey is not designed to do. For the most part, it isn't even necessary. I recommend against using these methods because they are prone to break (and cause crashes like these) whenever the implementation changes even slightly, as it did when #Warn was introduced.

Furthermore, IntegerFast should be used in place of Integer. Using Integer causes binary number write-caching (added in v1.0.48) to be disabled, for backward compatibility. (Side note: SetFormat is being removed in v2 in favour of a more flexible formatting function.)

I have missed to upload Struct.ahk with latest fix
Now it should work, sorry about that. Struct.ahk
