Brainfuck, 46 45 (63 with printable characters in input)
Compatible with Alex Pankratov's bff (brainfuck interpreter used on SPOJ and ideone) and Thomas Cort's BFI (used on Anarchy Golf).
The printable version takes the array first as a string, followed by a tab, followed by the starting string with no trailing newline.
Demonstration on ideone.

f=lambda n,k=1:`k`in bin(n^n/2)and-~f(n,k*10)
Try it online!
How it works
By XORing n and n/2 (dividing by 2 essentially chops off the last bit), we get a new integer m whose unset bits indicate matching adjacent bits in n.
For example, if n = 1337371, we have the following.
n = 1337371 = 101000110100000011011₂
n/2 = 668685 = ...

Extracts binary digits from n in reverse by repeatedly taking n/2 and n%2. Tracks the length of the current run r of equal digits by resetting it to 0 if the last two digits are unequal, then adding 1.
The expression ~-n/2%2 is an indicator of whether the last two digits are ...

Well, this is surprisingly competetive.
We define a function f(char*, char*) that takes the string as its first input and the array of characters to duplicate as its second input.

The main trick is in generating the numbers the new value must avoid. Keeping the reversed sequence so far in l, let's look at what elements might form a three-term arithmetic progression with the value we're about to add.
