20# Not all fuzzers can be compiled with --sanitizer=coverage.
21# The specific issue is that gofuzz.NewFromGofuzz is not supported when compiling with coverage.
22# The current status of the coverage build is that we do not break it for the fuzzers that cannot be compiled.
23#The reason that we don't break the build script is to create coverage reports for the fuzzers that compile.
