[Numpy-discussion] confusing recarray behaviour

[Jonathan Taylor]

Here is a pickle file with v and desc, v is just a list of tuples with 
integer and string entries. My point with my example is that when I had 
two identical lists (i.e. v[0:2] == V) one time I got an error, the 
other time I didn't and the traceback had no information, i.e. I 
couldn't get anywhere with pdb. I am using svn revision 2456.
