su, FFCall & crash

[Manuel Guesdon]

Hi,

Here is a crazy problem.
The system is a Mandrake2007 on a bi-xeon dual-core.
ffcall 1.10 rpm package is installed

I run the following attached test (FFCall/test00.m)

It works (there's an exception but this not the point) when I run it under 
valgrind. It also works when I ssh (same user) on the box or when I login 
directly on the box.

It dosn't works when I do a su (or a su --login), from root or even by directly 
logging under the user and doing a su user

I've put exactly the same environment for ssh test and su test and this doesn"t 
works.

It crash when calling the ff_callback (see GSFFCallInvocation.m) for __VAuint 
type.

I've attached 2 traces and ff_callback dissasembled code.

Any idea ?

Thank you !!

Manuel
