Comment (by anonymous):

 uh oh - your comment made me realize that I created a huge blunder.  I
 went and looked this up in the code.  It turns out that that original
 implementation used stack_construct which in turn used load_construct_data
 which permitted non-default constructors.  So the current implementation
 does use this - so it's likely breaking reads on existing archives !!!  So
 This can't be ignored.  I'll see what I can do about it.  As usual, making
 any kind of change turns out to have a lot more implications than first
 meet the eye.  The difficulty and effort required to write and maintain
 this library are way under-estimated.
