Hi all, I just got a compiler crash (Cython 0.17, 0.17.1 and current master) when trying to compile a call to a function returning an np.ndarray:
cimport numpy as np cdef np.ndarray[np.float64_t, ndim=2] trivial(X): return X def test(): # Uncommenting the following line, or removing the assignment, # prevents the crash: #cdef np.ndarray[np.float64_t, ndim=2] Z Z = trivial(np.zeros(4)) I'm aware that the program contains an error and it's not much of a hindrance to the project I'm working on, but the error message just isn't very friendly: Compiler crash traceback from this point on: File "/home/lars/src/cython/Cython/Compiler/ExprNodes.py", line 1528, in analyse_target_types Buffer.used_buffer_aux_vars(self.entry) File "/home/lars/src/cython/Cython/Compiler/Buffer.py", line 280, in used_buffer_aux_vars buffer_aux.buflocal_nd_var.used = True AttributeError: 'NoneType' object has no attribute 'buflocal_nd_var' More details at https://gist.github.com/4114677. I looked at Buffer.py and ExprNodes.py, but I couldn't figure out what exactly was going on. Could someone please look into this?
