Hi,

I tried out Cuis 7.8 and I'm experiencing a crash of the vm when I call an
FFI function which returns nil (NULL). I the previous versions (at least I
used Cuis 7.2) it worked and Smalltalk returned with nil.

You can reproduce it even by using the Tests-FFI, for example:

| t |

t := FFITestLibrary new ffiPrintString: nil.

In version 7.2: t is nil.
In version 7.8: vm crashes: terminated by signal SIGABRT (Abort)

Do you have any idea?

Br,
Tamas
