I'm running Python 3.4.3 and Cython 0.23.4 under Gentoo Linux. I think
I've found a bug in Cython. Steps to reproduce:
## test.py ##
import pyximport
pyximport.install()
import mymodule
print(mymodule.get(1, 2))
## mymodule.pyx ##
cdef int[2][3] arr = (
(0, 1, 2),
(3, 4, 5)
)
cpdef int get(int i, int j):
return arr[i][j]
####
`python test.py` fails with the following traceback:
