See http://xmlsoft.org/XSLT/bugs.html for reports, especially
testing with the latest versions of both libxml2 and libxslt,
and the need for the crash inputs (xsl + xml).

xsltproc ss/simple.xsl data/test.xml

Comment 4 William M. Brack 2004-03-09 15:47:30 UTC

This problem was caused by an overflow of space reserved for the 
compilation of attribute value templates.  I changed the coding to 
allow dynamic growth of the structure, which fixes the problem.  
Changes are in CVS (libxslt/attrvt.c)
