Backtrace with debug symbols

I run new doxygen release 1.6 on my project, I have a segmentation fault on a
specific xml file parsing. With 1.5.9 release it is ok.

Parsing file /PRIVATE/PATH/deployBin.xsd...
Reading /PRIVATE/PATH/deployDataMonitor.xml...
Segmentation fault (core dumped)

I activate printf function :
Entry 3 with name /PRIVATE/PATH/deployDataMonitor.xml type 0x400000 added to
(null) type 0x3000000
Entry::addSubEntry(/PRIVATE/PATH/deployDataMonitor.xml:0x2b7b940) to (null)
Segmentation fault (core dumped)

Parse this file leads to segmentation fault

Xml tag value seems to be cause to crash.

Comment 2 Dimitri van Heesch 2009-08-20 12:49:18 UTC

With version 1.5.9 doxygen didn't parse any XML files. With 1.6.0 it can,
assuming the file is a DBUS interface specification. 

In any case doxygen should not crash of course, but just for my information: did you explicitly tell doxygen to parse this file or was it just sitting there and
picked up "by accident"?

With 1.5.9 version it is useful to read just xml file content with doxygen html doc, so I tell doxygen to parse all xml files.

Works form me with 1.6.1 version.
