considering the repeating pattern, it may be some infinite recursion, perhaps
run with -dH and look at the backtrace in the coredump. also this code seems to
be the language frontend (the specfile parser in particular) that the initify

no dice, both 5.4 and 6.3 worked fine (save for a few -Wunused-but-set-variable
warnings).
