this statement was wrong.  addition raises AV too, but that depends on 
too many circumstances.  i've seen that command

   python -c "from peak.model import features"

stops segfaulting when i add 'import pdb' to the body of class structField.

it fails in function newWrapper, in the call to PyMem_NEW at line 1724.

by the way, it seems to me that PyMem_Del(wp) is missing before return 
NULL at line 1737 in that function.

in fact, i would like to stop this investigation.  mingw build is ok for 
us.  msvc would be more handy, but that is not worth the time spent.

thanks for your help.

best wishes,
