Both, I'd say. The crash is in line 100 of yasm.pyx, where it says:
cdef class __assoc_data_callback:
cdef yasm_assoc_data_callback *cb
def __new__(self, destroy, print_): # <=== HERE
self.cb = <yasm_assoc_data_callback *> \
malloc(sizeof(yasm_assoc_data_callback))
self.cb.destroy = <void (*) (void *)>PyCObject_AsVoidPtr(destroy)
#self.cb.print_ = <void (*) (void *, FILE *, int)> \
PyCObject_AsVoidPtr(print_)
The "__new__" method must be called "__cinit__".
Without closer investigation, I suspect that the relevant change in Cython
0.14 is that it knows about "__new__" being a staticmethod. However, for
cdef classes is silently translates "__new__" into "__cinit__" internally.
It seems like both don't work together.
