 We're experiencing an issue where ffmpeg seg faults for very large
 "-filter_complex_script" input files (roughly 3MB). The input file
 consists of a very large number of drawbox filters. The same processing
 pipeline works fine for smaller files, but seems to have an issue as the
 file size increases. Is there a hard limit to how large this file can be?
 If so, is there a "magic number" somewhere that we can increase and re-
 compile from source?

 Does anyone have any other thoughts or advice?

 Thanks in advance!
