 It is unclear to me, if this is a problem with the source file or with the
 gas-preprocessor.
 I used this gas-preprocessor:
 https://github.com/yuvi/gas-preprocessor.git

 How to reproduce:

 gas:
 checkout https://github.com/yuvi/gas-preprocessor.git
 chmod +x gas-preprocessor.pl
 sudo mv gas-preprocessor.pl /usr/local/bin

 ffmpeg
 checkout https://github.com/FFmpeg/FFmpeg
 exec following script:
 -------
 #!/bin/bash
