I don't have a Trac account yet, but wanted to report this bug with
the 0.16 RC. This function worked fine under 0.15.1:
@cython.wraparound(False)
@cython.boundscheck(False)
def is_lexsorted(list list_of_arrays):
cdef:
int i
Py_ssize_t n, nlevels
int32_t k, cur, pre
ndarray arr
nlevels = len(list_of_arrays)
n = len(list_of_arrays[0])
cdef int32_t **vecs = <int32_t**> malloc(nlevels * sizeof(int32_t*))
for i from 0 <= i < nlevels:
vecs[i] = <int32_t *> (<ndarray> list_of_arrays[i]).data
# assume uniqueness??
for i from 1 <= i < n:
for k from 0 <= k < nlevels:
cur = vecs[k][i]
pre = vecs[k][i-1]
if cur == pre:
continue
elif cur > pre:
break
else:
return False
free(vecs)
return True
gives this error:
python setup.py build_ext --inplace
