Please can you let me know how to get the patch / source / that fixes this ?
The bug # of the original bug ? Should I be building from GIT ? Which GIT tag ?
I'll try that next ...

selinux is disabled on my system, there were no SELinux attributes
in the string emitted by 'ls -dl' - and the python executable does
not link to libselinux - so you're saying that, in this code :
pat = r'''d......... # It is a directory.
\+? # It may have ACLs.
'\+?' is incorrectly requiring '+' ?
Surely this is a bug in the regexp code ?
Nope, I don't think it has anything to do with SELinux attributes -
when I remove the '\+?', the RE still fails :
$ cat test.py
import os
import sys
import re
pat = r'''d......... # It is a directory.
\s+\d+ # It has some number of links.
[^/]* # Skip user, group, size, and date.
/\. # and end with the name of the file.
'''
str = 'drwxr-xr-x. 25 root root 4096 Apr 20 15:28 /.'
if re.match(pat, str, re.VERBOSE) :
print "MATCHED\n"
else :
print "DID NOT MATCH"
$ LD_LIBRARY_PATH=`pwd` LD_PRELINK=`pwd`/libpython2.7.so.1.0 ./python ./test.py
DID NOT MATCH

This really frightens me - do you really believe that
"all three sizes must be the same" on an x86_64 ? :
test_dl
test test_dl crashed -- <type 'exceptions.SystemError'>: module dl requires
sizeof(int) == sizeof(long) == sizeof(char*)
That your dynamic linking module should give the impression in its
test script that it thinks 'sizeof(int)' (==4) should be equal to
'sizeof(char*)' (==8) is rather disconcerting to say the least -
and terrifying if it actually acts on this fundamental misconception
in its code - the fact that it crashed suggests maybe this is the
case. I'll see what happens with this test for the new code build
and raise another issue if not fixed.
