Possible same problem, local static variables:

boost-1_32\boost\spirit\core\non_terminal\impl\object_with_id.ipp(130,133).
boost-1_32\boost\spirit\core\primitives\impl\numerics.ipp(516)
boost-1_32\boost\spirit\debug\impl\parser_names.ipp(420)
boost-1_32\boost\spirit\utility\impl\chset_operators(511, 521)
boost-1_32\boost\spirit\utility\impl\escape_char.ipp(192)

boost-1_32\boost\spirit\phoenix\closures.hpp(404).

Debugging and tree_to_xml doesn't  work corectly in multi-threaded 
enviroment. Its use static ints for storing intendation info that should 
be moved to tls too.
