[Maz-o <1398898@xxxxxxxxxxxxxxxxxx>]

This entirely depends on the type and number of parameters that are
passed.

Rule of thumb: as soon as a 64bit parameter appears in the call, it is
likely that this code will do the wrong thing. Depending on the use of
the parameters, effects could range from nothing to complete crash, with
memory corruption in between.

Hint: It probably wouldn't be too hard to turn this bug into an attack
vector.

But who really cares about security when such a bug is being ignored,
despite having been identified four months ago, with a proper fix
submitted for all of that time...

Cheers,

Marc.
