Posts stand a better chance of being read by the right person if they
include the library name in square brackets at the beginning of the
subject line. For example, "[regex]" or "[filesystem]". The subject
line should not begin with "[boost]" as that is added automatically.

Are you saying that a data race occurs during static initialization,
and that causes a deadlock?
Does this always occur with programs that use Boost System, or only
when combined with Wave?
Have you tried to construct a simple test program that illustrates the problem?
