I tried the following and it works for me, the buffer code gets properly
discarded:
'''
cimport numpy as np
def disabled_usage(obj):
cdef object[int, ndim=2] buf
cdef np.ndarray[np.int32_t, ndim=1] buf2
if False:
buf = obj
elif not True:
buf2 = obj
return obj
'''
Could you try to find a minimal example that shows the problem?
