gdb log when createrepo stops by free problem

Description of problem:
With the latest libxml2 calling createrepo always hangs up by glibc detection
of double free or corruption on python.
gdb backtrace seems to be telling that the actual corruption is occuring
on libxml2 side.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Download some rpms
2. execute $ createrepo $(pwd)
Actual results:
gdb log attached

Expected results:
createrepo should not hangs up

Additional info:
With libxml2-python-2.6.32-4.fc10 this issue does not occur.

Hum, it's possible that some of the code done in the libxml_serializeNode
function in the libxml.c bindings for python is not very clean and clashes
with the new buffers types.

Comment 2 Daniel Veillard 2008-08-31 16:09:58 EDT
Bug confirmed on 2.7.0, I guess 2.7.1 will be out of the door tomorrow
so fix should show up really soon.
A really stupid mistake on my part.

 thanks for the heads-up !

Comment 3 Daniel Veillard 2008-09-01 11:32:28 EDT
libxml2-2.7.1 released, it fixes serialization in the Python bindings
which were broken in 2.7.0

798404 build (dist-f10, devel:libxml2-2_7_1-1_fc10) completed successfully

pushed to rawhide, I hope this fixes it,

Comment 4 Mamoru TASAKA 2008-09-01 12:57:46 EDT
With libxml2-python-2.7.1-1.fc10 I don't see this issue anymore.
