Category: None Group: None >Status: Closed >Resolution: Accepted Priority: 3 Submitted By: Mars Hall (marsipan) >Assigned to: Charlie Savage (cfis) Summary: invalid XPath causes segmentation fault on Solaris Initial Comment: Doing a #find using an invalid XPath indirectly causes a segmentation fault on Solaris. I say "indirectly", because the XPath eval error does not immediately cause the segfault; instead the segfault occurs at some point after the invalid XPath eval. On Mac OS X, invalid XPath does not cause the ruby app to exit. The error logged is: Error: Invalid expression. xmlXPathEval: evaluation failed /usr/local/lib/ruby/gems/1.8/gems/libxml-ruby-1.1.3/lib/libxml/node.rb:71: [BUG] Segmentation fault ruby 1.8.6 (2007-03-13) [i386-solaris2.10] The invalid path in question mistakenly used a double-pipe "||" instead of a single-pipe "|" for a logical "or". Correcting this XPath prevents the segfault, but ideally this XPath error should raise a ruby exception, not kill the process. ---------------------------------------------------------------------- >Comment By: Charlie Savage (cfis) Date: 2011-04-22 22:56 Message: This is fixed in the latest release.
