I want to implement continuous integrated fuzz testing for my c++ project, but I have to use GCC due to a dependency. I know there is fuzz testing for LLVM (libFuzzer). Is there something similar for GCC?

Seems AFL++ (American Fuzzy Lop plus plus) has a gcc_plugin

AFL++ is a superior fork to Google's AFL - more speed, more and better mutations, more and better instrumentation, custom module support, etc.

I think you can use AFL++ with OSS-Fuzz or ClusterFuzz to implement continuous integration.

note: I have no experience fuzz-testing, but I am pretty good with web-searches.
