Crash Accessing Field from Function inside Method

Archives Forums/BlitzMax Bug Reports/Crash Accessing Field from Function inside Method

Runs in debug mode, crashes without error in release mode after printing "in".

SuperStrict
Framework BRL.StandardIO

Type TTest
	
	Field s:String = "hello world"
	
	Method Emit()
		Function Out()
			Print s
		End Function
		
		Print "in"
		Out 
		Print "out"
	End Method
	
End Type

Local t:TTest = New TTest
t.Emit

Its not supposed to work either ;)

A function inside another function or method, is still a global function, its just not visible outside.
The reason it sometimes work, is because the Self pointer is still on the stack somewhere.

Pass Self as a parameter instead, i know not as good looking, but at least it wont hang at random intervals hehe

Yeah. It doesn't make sense that "s" would have scope inside a global function.

It should probably throw a compiler error.

Yeah. It doesn't make sense that "s" would have scope inside a global function.

But I could easily see how someone would think of it in that inheritable way.

Yeah, it's probably not supposed to work, but oddly it does in debug mode. Something similar works in some languages, especially the more functional-programming-oriented ones. Anyway, this should probably give an error at compile time.

Hi,

Yes, the compiler should be picking this up - 's' shouldn't be visible to the function.
