Hello,
I have a problem parsing XML files in different threads using the
load_xml method.
The program ends with a "Segmentation fault" and a backtrace similar to :
#0 0x0000000000000000 in ?? ()
#1 0x00002aaaab9d632b in __xmlParserInputBufferCreateFilename

I use perl 5.16.2, libxml2 2.9.0, and XML::LibXML 2.0012,, everything
configured with threads.
I suspect that the xmlInputCallbackTable (which is a static variable of
xmlIO.c) is being initialized/de-initialized each time a load_file
starts or ends (I noticed that in LibXML.pm/parse_file, _init_callbacks
is called).
Cheers,
Philippe
