I think there is a bug. Specifically, rbnum_to_nsnum from  
ocdata_conv.m should return an autoreleased object:

static BOOL rbnum_to_nsnum(VALUE rbval, id* nsval)
{
   BOOL result;
   VALUE rbstr = rb_obj_as_string(rbval);
   id pool = [[NSAutoreleasePool alloc] init];
   id nsstr = [NSString stringWithUTF8String: STR2CSTR(rbstr)];
   *nsval = [[NSDecimalNumber alloc] initWithString: nsstr];
   result = [(*nsval) isKindOfClass: [NSDecimalNumber class]];
   [pool release];
   return result; // **** should be return [result autorelease];
}
