Re: gawk: "please file a bug report"

Looks like the problem is the number type, not the array. I experimented
with Deni's example and narrowed it down:
v = "" A[ i ]; # coerce number to string, then: no error
#add new lines:
n=2;   gensub( /^/, "1", 1, n ) # generates the warning
print "typeof(n) " typeof(n) " after gensub n= " n
# output: 'typeof(n) "unknown" after gensub n= 2'   # (still 2, but not a
number?)
So, Gawk might check the gensub() 'target' for not-a-string ...
