To put it differently, if you think in terms of MRO, my custom type's MRO is
my_type_clear (from my type), subtype_clear (from PyTypeObject), etc
And subtype_clear incorrectly assumes that it is the first entry in the

New submission from Victor Milovanov :
I am trying to define a type in C, that derives from PyTypeObject.
I want to override tp_clear. To do so properly, I should call base type's

In my case it always happens in pymalloc_alloc when size == 5, e.g. when
accessing usedpools[10].
Specifically freeblock pointer in usedpools[10] is wy off (essentially,
seemingly random number looking like 0xX000) where it is supposed to be
