I get different errors everything I run it.  The command:

pi at raspberrypi:~ $ mythcommflag -v -f 11701_20190816033500.ts
2019-08-16 14:25:42.620785 C  mythcommflag version: fixes/30 [v30.0-60-gb9c1b41a6c] www.mythtv.org
2019-08-16 14:25:42.620900 C  Qt version: compile: 5.11.3, runtime: 5.11.3
MythTV Commercial Flagger, flagging commercials for:
    The Late Show With Stephen Colbert - Kirsten Dunst; Adam Devine; Lee Pace
Finding Logomalloc_consolidate(): invalid chunk size
Handling Aborted
Aborted

I’ve also seen segmentation fault, and invalid fastbin entry (free).
