digitalmars.D - classes: Error and Exception

The following gives "segmentation fault", but maybe it should throw an excetion
like running out of array limits? I I think that it is almost as common mistake
as running out of array bounds.


What do you think about this?

class Ca{
public:
int b;
}

int main(){
Ca a;
try{
a.b=1;
}
catch(Exception e){
printf("ERROR!\n");

}
return 0;
}

your code works for me.  i run it and it says ERROR!

i'm using windows though.  i suppose you're using linux?

Interesting, that means, that in Windows D can catch "Segmentation faults", but
in linux not.

Is it so Walter?

This is a known bug/missing feature on Linux. I'm pretty sure that Walter intends to implement this. Of course, if one of us writes some good example code for him, then it would be much easier for him...

My experience on low level coding for linux is pretty limited. If someone wants to donate the code for linux that will convert seg faults into exceptions, like the Windows code does in internal\deh.c, I'd love to incorporate it.
