Cannot access memory at address 0x0

[defumar]

Hi, it's me, again (sigh), I'm unsure whether I should post this on the KDevelop forum, the gdb one or qtcentre, so I'll start with the most specific one.
I'm new to working with KDevelop. Yeah, I guess I should read some docs about it. (I normally work with MSVS)

Here's the problem I'm having: I keep getting the following error when trying to debug: Cannot access memory at address 0x0. I've cut down my code and pinned down the problem to be at line 5, yet I'm still puzzled as of why it happens, I can't see what I'm doing wrong here. (naturally, it compiles just fine)

Right, so here's the code.

#include <QApplication>
 
int main(int argc, char *argv[])
{
	QApplication app(argc, argv);
 
	return 0;
}

#include <QApplication>

int main(int argc, char *argv[])
{
	QApplication app(argc, argv);

	return 0;
}
