Subject: memory leak in ruby or dumb mistake?


Hi, I've narrowed down a memory leak in my program to the extremely 
simple C extension at:

http://PATH.Berkeley.EDU/~vjoel/Task.tgz

Can anyone see anything I'm doing wrong?

The heart of the problem seems to be in calling the following method, 
Task#read, repeatedly, from an eval:

VALUE read_module_Task_method(VALUE self)
{
     Task_Shadow *shadow;
     Data_Get_Struct(self, Task_Shadow, shadow);

     free(shadow->value);
     shadow->value = 
strdup("foobar----------------------------------------");

     return Qnil;
}
