I don't think this is correct: various functions in addr2line.c seem to 
assume the buffer is always the same, and they call themselves 
recursively (e.g. rb_dump_backtrace_with_lines (sets binary_filename) -> 
fill_lines -> follow_debuglink (sets binary_filename) -> fill_lines -> 
...). With your patch, it would also cause the binary_filename pointer 
to be stale over runs.
