Being quite familiar with this problem, I was about to point you to 
rpmspec.c source for an example, but seems I never actually got to fix 
the problem there :(

So I'll have to point you to a freshly created pull-request instead:

But to summarise, simply call rpmFreeMacros() and rpmReadConfigFiles() 
after each attempted spec parse. This is a shotgun solution of course 
but there's no better way to reset the state at the moment.
