New submission from Filip Malczak:
Ive been using YAPSY to load plugins in one process. In this process I tried to
put them in queue, and in another process I read them from queue.
There was a problem with non-existing type of plugin in consumer process, so I
tried to serialize plugin instance by hand and deserialize by hand in consumer.
Both processes were created and started from main process, which passed them
both the same queue.
Law forbids me from showing the whole code, but I'm attaching file with code
pieces that generate error below:
Process ConsumerProcess-2:
