Memory error when copying XSL

[Ben Liles]

I am receiving a memory error when attempting to copy xsl. The only change in my code recently is that I'm now using a custom parser that has an additional resolver for resolving package names in includes.

File "/opt/apps/python/2.6/lib/python2.6/copy.py", line 79, in copy
  return copier(x)
File "xslt.pxi", line 456, in lxml.etree.XSLT.__copy__ (src/lxml/lxml.etree.c:109241)
File "xslt.pxi", line 656, in lxml.etree._copyXSLT (src/lxml/lxml.etree.c:110876)

exceptions.MemoryError

Could you provide example code that shows this error? Otherwise, it will be impossible to reproduce and track down.

An example is attached in a gzipped tar file. Unpack and run example/__init__.py with lxml in your system path in addition to the standard python libraries.

It looks like this is hiding a different error that occurs in libxslt while processing a copy of the stylesheet. Sadly, the function that does this in libxslt only returns a single error value, so lxml.etree just guesses that this was due to insufficient memory - apparently an incorrect assumption in this case. I'll have to take a closer look to figure out why an error occurs here.
