[issue2263] struct.pack() + numpy int raises SystemError

[engelbert gruber]

engelbert gruber <grubert at users.sourceforge.net> added the comment:

on ubuntu 8.04, Python 2.7a0 (trunk:69044) and numpy 1.2.1
("." is OK, "e" means SystemError)

* signed always works, longlong also.
* unsigned native works half of the time
* unsigned little/big endian never works
* the numpy type does seam to have any effect.

signed char          b   'int16'   .  <.  >.  'uint32'   .  <.  >. 
sys:1: DeprecationWarning: struct integer overflow masking is deprecated
unsigned char        B   'int16'   .  <e  >e  'uint32'   .  <e  >e 
signed short         h   'int16'   .  <.  >.  'uint32'   .  <.  >. 
unsigned short       H   'int16'   .  <e  >e  'uint32'   .  <e  >e 
signed int           i   'int16'   .  <.  >.  'uint32'   .  <.  >.
