No, it won't release any fumes, bit it might relinquish its hold on the
parts you wanted sealed.   Its not really designed for any serious heat

You would have been better served to use Polyurethane sealant.  Comes in a
caulking tube, in several decorator colours and is reliably permanent.  Its
what we use to fasten windows into buildings large and small and is more
elastic than other types.
