(not really sure if this will really help figure out the problem, 
but...)

You can break on it (probably smth like "break _d_dso_registry"), 
then continue when execution is stopped at the start of the 
function (probably "c"), and count how often the breakpoint is 
triggered (keep "c"), before the program exits.
