I can't get to my notebook at the moment, but I seem to remember that it was
because when unwinding an exception, registers were "unsaved" unnecessarily,
which corrupted the return address (in A3?). I'll try to find out what it
was. In any case, so much else has changed since then that my change may be
obsolete.
The change was applied to 1.0.7 - I don't know how valid it is for later
versions.
