I read some _very_ old threads, and apparently a null dereference 
raised an exception only on Windows, while on linux it still 
needed work to be implemented properly. Things probably changed a 
lot in the mean time, but I think the default behaviour should be 
"throw an exception" on every platform. A core dump with zero 
extra info is bad. I don't care if 95% of times you can fire up a 
debugger and find out what happened. This is not something that 
can be always done.
