Since Tuncer did not submit all the info he has, let me add that the 
behavior reported in his mail exists in the *master* branch of OTP and 
*not* in the maint branch which works correctly in rebar's code base.

It's unlikely that this is a dialyzer issue, as AFAIK dialyzer's code is 
the same in these two branches, but it's most likely either due to some 
erroneous spec that was introduced/changed in the master branch or a 
problem in rebar's code base.

IMO, Tuncer should have checked the latter before filling the report. It 
would be nice if he did that.
