Hook fail asserts to prevent false positives with AFL

Compile.txt

go build -buildmode=c-shared -o fail_assert.so main.go

Then just LD_PRELOAD the generated .so

main.go

package main

import (
        "C"
        "github.com/rainycape/dl"
        "log"
)

func main() {}

//export __assert_fail
func __assert_fail() {
        lib, err := dl.Open("libc", 0)
        if err != nil {
                log.Fatalln(err)
        }
        defer lib.Close()

        var exit_func func()
        lib.Sym("exit", &exit_func)

        exit_func()
}
