Building chromium with clang coverage

I am trying to build a coveage build for chromium and run into the following issue:

“`

Event after fixing the `FuzzerInterceptors.cpp` file, there are stil errors that persist. Below is my compilation approach:

“`
gn gen out/coverage –args=”’
dcheck_always_on = false

is_debug = false
use_clang_coverage = true
is_component_build = false
optimize_for_fuzzing = false
use_remoteexec = false
is_asan = false
use_libfuzzer = true
symbol_level = 2”’

autoninja -C out/coverage
“`

If anyone has a fix, do let me know
