Failing in objc_get_class

[Sebastien Pierre]

Hi all,

I am using objc_get_class to try to retrieve an Objective-C class object. The 
problem I encounter is that if the given name does not correspond to an 
existing class, I get :

objc runtime: cannot find class Pouet
Abandon (core dumped)

I tried to set the fallback hook "_objc_lookup_class", but this does not help. 
Is it possible to prevent objc_get_class from terminating the process, or maybe 
to test the actual existence of a given class ?

TIA,
