[lxml-dev] a different segfault

[Roger Patterson]

Hi Stefan et al.

I am getting a mysterious segfault using the XSLT lib.
Basically, if I have:
    <xsl:strip-space elements="*"/>

in my transform, I get the segfault, if I remove that line, it works fine.

Now, I haven't distilled it down to a succinct example yet, and my 
transform and code are pretty large, but I was wondering if anyone else 
has experienced this?

cheers
