code

for part in cargs.coverage_cmd.split(' '):
            if part[0] == ' ' or part[0] == '-':
                continue
            if (which(part)):
                found_exec = True
                if not cargs.disable_gcov_check and is_bin_gcov_enabled(part, cargs):
                    found_code_cov_binary = True
                    break

if coverage_cmd has multi space, the value 'part' will get a '' and making binary exit.like this

afl-cov -d /out --live --coverage-cmd "LD_LIBRARY_PATH=../lib/  ./tiffinfo -D AFL_FILE"   --code-dir /src/libtiff --genhtml-per-min 1440 --background
