           Summary: Using perl's XML::LibXML Xpath function makes perl to
                    crash
           Product: Fedora Core
           Version: fc6
          Platform: i386
        OS/Version: Linux
            Status: NEW

Description of problem:
I study xpath functions using perl's XML::LibXML and the result of one of my
tests makes perl to end abnormaly dumping a backtrace and the memory map. I
would expect either 0, undef, the xpath's "Invalid expression" or compile
(sytax) error to result no matter how the xpath function is build or stated in
the code.


Version-Release number of selected component (if applicable):
2.6.20-1.2933.fc6 #1 SMP Mon Mar 19 10:42:48 EDT 2007 i686 i686 i386 GNU/Linux
perl-5.8.8-10
perl-XML-LibXML-1.58-2.2.2.1


How reproducible:
a single occurence - a technology study

Steps to Reproduce:
1.
2.
3.
  
Actual results:
SIGABRT

Expected results:
0, undef, the "Invalid expression" Xpath error or compile (sytax) error
