Re: [xmlvm-users] CGRect & memory issues

[Arno P. <ar...@pu...>]

this should be unrelated to CGRect. CGRect is a Java class like any 
other. This seems to be related to the reference counting mechanism of 
the Objective-C backend. When assigning a new value to myrect.size, the 
old value needs to be released first. This is something that should be 
done with the reference counting mechanism and if there is a problem I 
am really surprised because it would indicate a fundamental problem with 
all setters.

Can you mail the generated Objective-C code?

Either way, its really time to move to a proper garbage collector.
