That approach is not supported and will crash at runtime in some circumstances.
Nobody has tried to make a list of precisely which cases will and will not
work, so you're on your own here.
For example, if you code has a category on NSTableCellView then it will crash.

Tried, by making Cocoa & X.frameworks as Weak linking(Optional) under Link
Binary With Libraries section of the application target, but still the same
issue. It seems, I am missing something.

I'm setting 10.6 SDK as my base SDK, but my minimum deployment target is 10.5.
Therefore NSCache will not be there on 10.5.
I th

This workaround might help defeat the optimizer:
// was: if (&function != NULL) function();
void * volatile function_p = &function;
if (function_p != NULL) function();

How can I do to solve a problem like this and have an application that
uses weak linking and works on both platforms ?
This is due to a configuration error when the HIServices and HIToolbox

We're trying to compile our application so that it can run under 10.5 &
10.4 using weak linking (this is required for us other libraries). Our
software is based on wxWidget and so for the moment we're evaluating the
possibility of running the minimal sample from wxWid
