There were a few issues with the oss-fuzz integration from commit
8373f09854 ("build-sys: add oss-fuzz
support").
When building on OSS-Fuzz, the projects should use the provided CFLAGS
and CXXFLAGS and don't append any extra sanitization / fuzzing flags.
$LIB_FUZZING_ENGINE is defined to set the library to link to, and it
is a c++ library, so we should build fuzzer with c++...
Now --enable-fuzzer is only used for -fsanitize=fuzzer.
Add a tests/fuzz-main.c as fallback, to run the corpus on other builds.
