wondering if the problem lies with `free_module.tensor_constructor()`
being a cached_method and something is being improperly stored...
The failing assertion is
{{{
File "/mnt/storage2TB/patchbot/Sage/sage-5.8.beta0/local/lib/python
/site-packages/sage/categories/modules_with_basis.py", line 1387, in
__call__
assert(x.parent() is self.domain())
}}}
I can hardly imagine that there is yet another premature deallocation via
weak references in play. After all, both `x._parent` and `self._domain`
are just plain strong references.
