Thanks @MarcoFalke
My current understanding of this is it’s not due to Fuzz Introspector but rather LTO (https://github.com/ossf/fuzz-introspector/issues/48#issuecomment-1063163173). When I debugged it ( https://github.com/ossf/fuzz-introspector/issues/48#issuecomment-1063055164) I could not locate the error in Fuzz Introspector but just in some llvm code, and the issue occurred with and without fuzz introspector.
atm there are two different patches going on: the local ones from here and the ones already pushed to OSS-Fuzz. Ideally the patch we have here should be removed in favour of using the patches in upsteam OSS-Fuzz. I haven’t looked at doing this yet, but am not sure if the upstream OSS-Fuzz patches are fully working with a local set up – @Navidem there were some issues with running the fuzz-introspector set up in OSS-Fuzz locally, is this fixed?
For that reason I think it shouldn’t be bumped atm because it will mix the two patches together, which will inevitably fail.
There were two major things changed recently in the compiler plugin: (1) we updated to latest LLVM version and new plugin manager, and (2) we add a global variable as a tag in the binary (this is a “major” change since it means now we add content to the module whereas previously we just observed). This issue could be related to that, potentially.
