-Subject: [PATCH] asn1_find_node: added safety check on asn1_find_node()
-
-This prevents a stack overflow in asn1_find_node() which
-is triggered by too long variable names in the definitions
-files. That means that applications have to deliberately
-pass a too long 'name' constant to asn1_write_value()
-and friends.  Reported by Jakub Jirasek.
