I work on the migration of an application compiled under Code Warrior towards Xcode 2.4 in universal.
For the moment, the powerpc version work correctly, however I have problems with the intel version.
 
This is the problem:
 
I have asm (from a sript) code which calls functions on objects and sometimes, at the call time instead of the call to the dyld__stub__name_of_the_function we have a jump into dyld_stub_binding_helper_interface function (although all the lyrairies are linked statically ….) and it crash. 

The Mac OS X ABI requires that the stack be 16-byte aligned at the site of each call instruction on Intel.  When the stack isn't 16-byte aligned at the site of a call, you'll crash in dyld_stub_binding_helper.  See <http://developer.apple.com/documentation/developertools/Conceptual/LowLevelABI/Introduction.html> for documentation of the ABI.

Hope this helps,
Eric
