if (! (flags & PARSEFS_NOAR)
    && tp == tmpbuf && tp[0] != '(' && tp[nlen=1] != ')')
                                                  ^^
                                                  should be '=='
-----------------------------------------------------------------

It occurs indexing out of bounds when handling the following prerequisite
detected. Above if condition becomes true 
even if the file is not a form of archive member reference.

read.c: 3034
    e = next_token (e);  // At here, index out of bounds occurs

I've used electric fence (http://perens.com/FreeSoftware/ElectricFence/) for
detecting this.
