I'd test it character by character instead of testing long strings. I'm not too fluent in perl, but hopefully the logic on this should be followable:

Code:
$ cat palindrome.awk
BEGIN { FS=""; ORS=""; }

{
	for(N=1; N<=NF; N++)
	for(M=N+1; M<=NF; M++)
	{
	# If it does not begin and end on the same char, not a palindrome
		if($M != $N) continue;

		A=N ; B=M; P=1;

		# Test towards the middle until A and B cross
		while(P && (B > A))
			if($(B--) != $(A++) ) P=0;

		if(!P) continue;	# Not a palindrome

		printf("Palindrome, %d-%d: ", N, M);
		for(A=N; A<=M; A++) print $A;
		printf("\n");
	}
}
$ echo "AGCTAGCTCGAAGGTAG" | awk -f palindrome.awk
Palindrome, 5-11: AGCTCGA
Palindrome, 6-10: GCTCG
Palindrome, 7-9: CTC
Palindrome, 10-13: GAAG
Palindrome, 11-12: AA
Palindrome, 13-14: GG
