+This indeed the same as bug #60550. The attached sample should be 
+more consistent in reproduction since you can easily configure the 
+size of the matched string.
+The problem comes from the nature of the implementation which is VERY

+and in the atached case with a param of "100" the stack depth 
+necessary is probably 10K calls.
+A modification of the implementation to use a loop instead of 
+recursion in several key places will probably prevent the stack
