Description
Exiv2 is currently not re-entrant. I'm aware of the following problems, but maybe there are more:
+ It uses the old versions of some C/Posix functions instead of the *_r version.
+ Construction of the Image and Makernote factories accesses static variables without any protection

#439: Added optional parameters to XmpParser::initialize() to work around thread-safety issues (Jonathan Potter, GP Software)
History

AFAICS This is finally fixed with the removal of the complex Makernote registration logic.

Exiv2::XmpParser::initialize and Exiv2::XmpProperties::registerNs are not thread-safe, see http://bugs.kde.org/show_bug.cgi?id=166424

And use d private internal classes to host privates members/methods, to improve bianry compatibility and clean up code... This is very important for a library.
Look here for details from KDE project :
