oob read in handle_dot_label

Reported by Joseph Bisch | December 31st, 2016 @ 05:59 PM

The attached input file will cause yasm compiled with ASan to report an out of bounds read in handle_dot_label. I am also attaching the ASan output.

This was found while fuzzing yasm with afl.

Steps to Reproduce:

1) Compile yasm with ASan.
2) Create a file with the contents "$.." (without the quotations). For example, let's say we named it input. Alternatively, just download the file I attached here.
3) Run "yasm input".
4) Observe the ASan output.
