yes, and store it in the memory on the address of $var! there is really
no logical reason for me why this should not work.

this 'old' reference problem is known to me

i also have in mind that this new change with 5.1.2 has still something
to do with this, but not on the technical side but on the developer side
(as some developer changes this behavior or something what leads to this
new behavior with 'old' reference problem in mind), but i don't agree
that the old behavior was not correctly working or lead to any memory
corruption, the 'old' reference problem is a little bit different!

i give the function a valid variable, as required by call-by-reference,
i just assign a value just before passing it to the function!


p.s.: bist du auch auf der deutschen php mailingliste: php at phpbar.de?
