Your stack overflow seems to have occurred while doing a sort, which is
rather surprising, as the stack depth for a QuickSort should only
increase with the log of the number of nodes to be sorted.
Try a different XSLT processor. XSLTC is fast but isn't the most
reliable.
Other things you could try:
(a) put the xsl:if test
<xsl:if test="generate-id(.)=
> generate-id( $currencies[ @CURRENCY =
> current()/@CURRENCY ] )">
into a predicate in the select expression of the xsl:for-each
(b) replace the test in this xsl:if with a key. As written, your code is
likely to have O(n^2) performance.
