ORA-03113: when using xmltransform

Question

After messing with xslt I ended up with ORA-03113.
db version is 11.1.0.6
test is reproducable with the following case:
SQL> with t as (select xmltype('<?xml version="1.0" encoding="UTF-8"?>
  2   <ns1:ResourceAvailabilityNotification
  3   xsi:schemaLocation="http://schemas.abcdef.com/resourceavailabilitynotification"
  4   xmlns:ns1="http://schemas.abcdef.com/resourceavailabilitynotification"
  5   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  6    <ns1:Header>
  7      <Id iid="a">String</Id>
  8      <CallThreadId>String</CallThreadId>
  9    </ns1:Header>
10  </ns1:ResourceAvailabilityNotification>') xcol from dual)
11      select xmltransform(xcol
12        ,xmltype('<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >
13                   <xsl:template match="*">
14                    <xsl:element name="{local-name()}" namespace="">
15                     <xsl:apply-templates select="@* | node()" />
16                    </xsl:element>
17                   </xsl:template>
18              <xsl:template match="@*">
19               <xsl:attribute name="{local-name()}">
20                <xsl:apply-templates select="."/>
21               </xsl:attribute>
22              </xsl:template>
23                  </xsl:stylesheet>')) xml
24     from t;
ERROR:
ORA-03113: end-of-file on communication channelin the trace file:
ORA-07445: exception encountered: core dump [qmxdCreateFragment()+72] [SIGSEGV] [ADDR:0xB0] [PC:0x61C67D2] [Address not mapped to object] []I guess the problem is in
<xsl:attribute name="{local-name()}">
  <xsl:apply-templates select="."/>
</xsl:attribute> After changing the "apply-templates" to "value-of" then it works.

Ants,
I run the test on my laptop Windows XP 32 + Oracle EE 11.1.0.7.0. I broke off the statement after my machine was 100% CPU bound for over 15 min.
I used a local BEQ SQL*Plus connection to connect to the database. The database showed in that time no trace or any indication of a segmentation vault.
