Sorry, I have been gone for a while.
I tried to recreate the Problem, this is what I get:

When I run the code below (A7.86.6) the program does not compile properly, it crashes ("acknex.exe hat ein Problem festgestellt und musste beendet werden") leaving the acklog.txt in the following state:
Code:

And here's the code:
Code:
#include <default.c>
#include <acknex.h>


#define NDEBUG

void debugFct(char* funct);


#ifdef NDEBUG
#define wait(i) do{char *funct; engine_gettaskinfo(0, &funct, NULL); debugFct(funct); wait(i); } while(0)
#endif


void debugFct(char* funct) {
	diag(funct);
}

void loopFunctions() {
	int i = 0;
	while(1) {
		diag("\n");
		diag(str_for_num(NULL, i));
		wait(1);	
		i+= 1;
	}
}


int main() {
	wait(3);
	loopFunctions();
	wait(3);
	sys_exit("");
}
