Summary0000140: hit asserts send SIGABRT leading to unplanned exit
Descriptionfuzzing with stock afl found some binary magic files, which will run into code asserts, which will lead to an abrupt:

    Aborted (core dumped)
    echo $?
    134

when seccomp is compiled in, we get:

    Bad system call
    echo $?
    159


not sure if you like the output or if you want to exit the program with a more userfriendly message?
Steps To Reproduce    git clone https://github.com/file/file.git
    cd file
    export CFLAGS="-g -fsanitize=address -fno-omit-frame-pointer"
    autoreconf -i
    ./configure [--disable-libseccomp]
    make all
    ./src/.libs/lt-file -m ~/test3.mgc /etc/services
