Description John Lind 2020-07-19 16:18:02 UTC 
I am running version 1.0.8 on FreeBSD on a Raspberry PI 3 Plus (arm64).  Things start out just fine, but then all of a sudden, the output file quits growing and one of the CPU cores is 100% consumed by bzip2.  I have waited several minutes, and it just doesn't seem to progress any farther.  The filesystem is only 21% full and no errors are posted to messages.

If desired, I can submit the log file causing the problem - but it's 138Mb so I don't want to do that unless necessary.

FreeBSD 12.1-RELEASE r354233 GENERIC  arm64

We need a bit more information to see what is going on.

Do other files compress correctly?
Does the same file compress on a different architecture with the FreeBSD 1.08 bzip2 binary?

Could you try to figure out where the process is stuck?
For example by attaching gdb and generating a backtrace?

Could you try running the bzip2 testsuite against your binary?
