awk dies trying to access NF

[adbennet]

simple test case
$ awk -- '{print NR;}'
foo
bar
^C
1
2
$ awk -- '{print NF;}'
foo
bar
^C
==FATAL
On looking at this again, it actually prints out NF before dying.

$ awk -- '{print NF;} END {print "bye";}'
foo bar
^C
2
bye
==FATAL

I can reproduce the issue. It's related to the memory reset at the end of awk (the freeTree function in run.c). I'm investigating.

I've submitted a partial fix on https://github.com/holzschu/ios_system
You'll have to recompile and sideload (obviously), and it's not 100% robust yet, but it crashes less often.
