py-lxml @3.3.5 Bus error from lxml after importing tkinter

[radaroutthere@…]

The following Python code generates 'Bus error: 10' -

import tkinter
from lxml import etree

root = etree.Element('test')
xml = etree.tostring(root)

If I reverse the order of the imports, the problem doesn't occur.

Yosemite. Reproduced under both Python 2.7 and 3.4 (adjusting the name of the tkinter module, naturally). I have tried uninstalling and re-installing lxml.

I have filed a bug in the Python LXML bug tracker - ​https://bugs.launchpad.net/lxml/+bug/1384102

I have also narrowed down the problem to line 126 of /src/lxml/serializer.pxi -

tree.xmlOutputBufferFlush(c_buffer)

I can well imagine that's not the root cause, but it's the line at which the bus error is produced, and it's a place to start.

I believe this was caused by the problem documented in #45711 where libxml2 was being built incorrectly on 10.10. That problem is now fixed. Try upgrading your ports.

Yeah, seems to be all good now. Thanks very much!
