D - Strange Problem with class

Hi, I have the following code that will get my CPU usage to 100% and never
terminates:

import stdio;

class bo_template {
int name = 1;
}

int main ()
{
bo_template bo_test;
printf("%d\n", bo_test.name);
return 0;
}


Any idea, what the problem is?

Yes, bo_test is not initialized. You need... bo_test = new bp_template(); It seems that in the Windows version of DMD a null object reference seems to go off into la la land.

Hi, :-| mea culpa. Of course this should be done. I'm programming with to much scripting languages where you just mention objects an get them.

Yes, that's the case. It should give a runtime error because of 0-object reference usage. Robert

bo_test is pointing to null here.
