[Pyrex] c-code mis-interpretation

Description

I found a small bit of code that gets compiled incorrectly to c. A sample is:

def unlist():
        lst = [1,2]
        lst,m = lst

The translated c-code from this will produce an Unindexable exception. This results from the fact that the variable "lst" is bound to the first element of the list (the integer 1) before the second element is extracted from "lst". Hence it tries to unpack from the integer rather than the list.

  • Milestone set to sage-2.9

This is a rather old bug. We should verify that the problem still exists.

tagged for 2.9, hopefully to be resolved during Sage Bug Day 2.

Cheers,

Michael
