Subject: Problem in NSBundle while loading categories


Hi all,

With some of the recent changes to NSBundle, my app crashes when it tries to
load a category contained within the bundle.

I traced the bug to the _bundle_load_callback function within NSBundle. When
a class is being loaded the "theClass" parameter is present but when a
category is being loaded only the "theCategory" parameter is present. The
function crashes when it tries to access the "theClass->name" variable, but
this is not present when a category are loaded. I changed the function as
follows and now everything works fine. 


void _bundle_load_callback(Class theClass, struct objc_category
*theCategory)
{
    const char *clsName;

   NSCAssert(_loadingBundle,NSInternalInconsistencyException);

   if (theCategory != 0)
     clsName = theCategory->class_name;
   else
     clsName = theClass->name;

  if (strlen(clsName) > 12 && strncmp("NSFramework_",clsName,12))
    return;

  ...The rest of the code as it was
}

Hope this helps to fix the bug

Regards
Gerrit van Dyk
