Plus a problem with NULL pointers being treated wrong in expressions
(after setting a pointer to NULL, comparing it to NULL in an expression
would yield a FALSE).

Afaik this problem is appeared only in the 68k version of the original
Tornado 2.0.2 compiler and was fixed with a later patch. Anyway:
compilers built from the sources available at SNS are not showing this
bug. (That's why we rebuilt even our HP-UX based compiler from the SNS
sources.)

Seems you have to choose which bugs you prefer ...
