If this is something disclosable please do so, because currently ruby lacks such thing. I fuzz ruby (in this case miniruby binary) with American Fuzzy Lop fuzzer (http://lcamtuf.coredump.cx/afl/). My testing corpus contains files from various open source projects written in ruby. It's all :-) ---------------------------------------- Bug #13234: Infinite recursion (stack overflow) in parse_char_class() https://bugs.ruby-lang.org/issues/13234#change-63050 * Author: Kamil Frankowicz * Status: Closed * Priority: Normal * Assignee: * Target version: * ruby -v: * Backport: 2.2: DONTNEED, 2.3: DONTNEED, 2.4: REQUIRED ---------------------------------------- After some fuzz testing I found a crashing test case.
