[bug-gawk] Possible regression of SYMTAB

[Assaf Gordon]

Hello,

Playing around with SYMTAB, I think there's a regression when creating a 
variable directly in SYMTAB in the current version.

Test case:
===
$ printf "1\n2\n" | ./gawk '{SYMTAB["POS"]=1 ; print $POS}'
1
gawk: cmd. line:1: (FILENAME=- FNR=2) fatal: internal error line 175, file: 
interpret.h
===

This works with 3.1.8, 4.0.1, and upto revision 
eb2698f49247c94c84e1e2c2304ba94d96c89bc9 ,
but fails starting with revision b9a82851866f84ca306a2802b4ca50089a2fe683 
(which is aptly named "First cut at SYMTAB and FUNCTAB.").
