p.s. that is the reason it is not turned on by default, btw.

Thx! That at least triggered an exception. However the line
number for the innermost function is wrong. For instance
1 void boom()
2 {
3 int* y = null;
4 *y = 42;// boom
5 }
gives stacktrace
etc.linux.memoryerror.NullPointerError@src/etc/linux/memoryerror.d(325)
