For what I've learned, apparently the creation of the node goes into the 
undo queue, and this queue has a limited length. Once the node reaches 
the other end of the queue, its destructor is called and any dynamically 
memory allocated is therefore deallocated, making the node is unusable. 
If memory has been allocated using Maya's own method (MDataBlocks) then 
this memory is still accessible. The memory is only deleted when the 
node itself reaches the end of its lifetime, and this is handled by Maya.

I'm not quite sure if this is it (I haven't quite got it completely 
clear in my head). In any case, the crash in Linux occurs as soon as the 
program returns from the first call to the node to compute its results, 
so I'm not convinced that undo queue even comes into it. I hope there 
isn't something deeper and more subtle going on.
