[py-dev] py.test error with cygwin update

[odonian at gmail.com]

I've been happily using py.test for about two months without problems
with an older version of cygwin (maybe 3-4 months old; sorry, don't
have the version number) and python 2.3.4.

Just recently I updated the cygwin environment, and now py.test keeps
failing; I have tried re-installing the py lib, re-installing cygwin,
and tried different versions of python (2.3.4, 2.4.1).  But this error
keeps coming up when running py.test, regardless of any other
command-line arguments (i.e. whether it's run in test collection mode,
or fed a specific test file, this error shows up):


Traceback (most recent call last):

    clsname = py.std.errno.errorcode[eno]
KeyError: 136

Since this didn't show up before, ever, I'm guessing paths are somehow
handled differently in newer cygwin versions, but hard to imagine why
it would change that much.  I have tried catching the above particular
KeyError for the errorcode dictionary, but that only causes another
problem elsewhere.  Any help would be appreciated,

S.A.
