It does look like an awk bug:

$ echo | /4/usr/bin/awk '{ x = 2147483648; print $x }'
awk: cmd. line:1: (FILENAME=- FNR=1) fatal: attempt to access field -2147483648

$ echo | /4/usr/bin/awk '{ x = 2147483647; print $x }'
*blank line*


$ echo | /5/usr/bin/awk '{ x = 2147483648; print $x }'
/5/usr/bin/awk: trying to access field -2147483648
 input record number 1, file 
 source line number 1

$ echo | /5/usr/bin/awk '{ x = 2147483647; print $x }'
*core dump*
