(closes issue #11903)
Reported by: atis

Many thanks to atis for spotting this problem and reporting it.
The fix was to straighten out how items are placed on and removed
from the file stack. Regressions as well as the provided test case
helped to straighten out all code paths. valgrind was used to make
sure all memory allocated was freed.

Sorry for not solving this earlier. I got distracted.

Added the ntest23 regression test, which is mainly a copy of ntest22, 
but with a few juicy errors thrown in, to replicate the kind of 
error that atis spotted.
