It seems incompatible with the newest version of the SpiderMonkey engine. I follow the profile guidance to build the js of SpiderMonkey. There is no problem running js alone, but the problem occurs when running with the following command. I've tried different build methods, but none seem to work. My system is Ubuntu 20.04.5 LTS (GNU/Linux 5.15.0-56-generic x86_64). I have run fuzzilli for jsc and d8 with no problem. But it turns into a fatal error on SpiderMonkey js. Can you instruct me on some solutions?
Are you using the latest Fuzzilli version and JS engine patches? From the output you pasted it looks like your Fuzzilli version is at least a couple months old?
You can also try the REPRLRun binary to debug issues with the target engine: swift run REPRLRun path/to/js_engine --any-flags-for-js-engine that may tell you more about the exit code reported by the target.
