Hi there,
i have a bug here that relates to neko's gc finalization. I have many objects
of the same kind that in their finalize method unregister from a global list,
so the finalize method is not threadsafe.
It seems it is called a few times in parallel, though. I see two options for
what's happening:
1) boehm-gc indeed somehow finalizes things in parallel (although i dont see
that would make much sense)
2) as the bug occurs primarily when i use more than a single thread, i suspect
the gc is triggered in parallel from different threads. Could this happen? If
so, how could i avoid it?
I think that Boehm GC can perform parallel sweep phase, and thus
finalizers might be called in parallel threads. You have to make your
global list MT-safe by using a lock.
Try to include (NEKO)/vm/context.h and you can use context_lock_new
context_lock , context_release and context_lock_delete.
Best,
Nicolas
