Dev-C++ Class Browser Problem

[MacC]

Hello

I have a problem with the DEV-C++-IDE (v. 5.7.0).

At a specific point in my code the following function appears.

int ReadStdInput(char** out) {
	int PosMax = 1024;
	char input;
	char validInput[PosMax+1];
	for(int i = 0; i <= PosMax; i++){
		validInput[i]=0;
	}
	[...]
	
	return 0;
}

The problem is, that the variables char input, char validInput[PosMax+1], int PosMax and even the "i" in the for-loop are appearing in the class-browser of DEV-C++ among the other global variables and functions.
I don't have any classes.
However this problem doesn't exist with any other project file.
And only this particular function is affected by this problem -> no other local variables are shown

Thanks in advance
