Double Free?

[Blackveiled]

Okay, some triggers I have right now, they keep sending double free messages, can I get some input on how to prevent them from saying this?

 

[PurplePoot]

Double Free of Group, you mean?

Screenshot or it didn't happen. (In this case, a picture is worth a thousand words)

Also, the GUI/JASS of the trigger that's firing it.

 

[Blackveiled]

There you go, I really do not understand this error though.

What is a double free?

 

[PurplePoot]

You remove ChargePointArray[1] before the if-statement, then you remove it again inside the if-statement.

 

[Kitabatake]

Does this double free of group cause lag or leaking?

Since I just got one in my physics system I'm developing...

 

[Xelephant]

double free wont work on without grimoires debugger. Because the Trigger dont know the group you're reffering too. You should only remove the variables at the very end of your Trigger. Unless you have a skip action in it.

I have no clue what you are even on about. What do you mean by double free of group and why is it even displaying it.

Unless you actually inform us what this error means no one can help you.

Double free is when you remove a variable twice. In this case, udg_ChargePointArray[1]

war3err detects it with groups aswell, and debug mode in vJass detects it with structs.

 

[PurplePoot]

It's actually when you try to destroy something that can't be destroyed, it just assumes it's double free.

I'm pretty sure

local location loc
call RemoveLocation(loc)

would display Double Free of Location.

And DSG, that's exactly what he was asking.

And Kita, I'm pretty sure it will crash the thread.

 

[HINDYhat]

Wouldn't it display:
Uninitialized variable "loc" in function BLAH.

 

[PurplePoot]

Hmm, yeah, it actually probably would.

Blah, if you removed it 3x you'd probably get two "Double Free"s though.
