I need a target executable for some test code that exits due to a SIGSEGV

Right now I have some code like this:

//go:generate bash -c "cc -x c  <(echo 'int main() { return *(int*)0; }') -o segv.bin"

func TestSignalledSegV(t *testing.T) {
    if _, err := os.Stat("./segv.bin"); errors.Is(err, os.ErrNotExist) {
        t.Skipf("To enable this test, run go generate ./...")
    }
    cwd, err := os.Getwd()
    require.NoError(t, err)

    k := scriptJobTest(t, `
        echo start
        exec `+cwd+`/segv.bin
    `)
    k.requireOutput("start")
    k.requireTerminalState("signal: segmentation fault (core dumped)")
}

I’d like to eliminate the need for an external C compiler for the test.

I tried some code like this:

    var f func()
    f()

Or even this:

    p := unsafe.Pointer(uintptr(0x1000))
    f := *(*func())(p)
    f()

but instead of terminating due to SIGSEGV, it hits the fault handler and ultimately does an exit(2)

How do I disable the fault handler?
