Playing a bag recorded with file compression segfaults

[audrow]

Description

When I try to play a bag that has been recorded with the compression mode zstd and format file, I receive a segmentation fault when I try to play that bag.

Expected Behavior

I expect to have the bag play.

Actual Behavior

The bag seems to open and then a segmentation fault occurs. Here is the printout.

[INFO] [1589568927.962724388] [rosbag2_storage]: Opened database 'compressed_bag/compressed_bag_0.db3' for READ_ONLY.
Segmentation fault (core dumped)

To Reproduce

0. In one terminal, create a publisher:

   ros2 topic pub /foo std_msgs/msg/String data:\ \'Hi\'\ 
   

1. In another terminal, record a bag:

   ros2 bag record --compression-format zstd --compression-mode file --output compressed_bag /foo
   

2. Hit Ctrl+C to stop recording the bag.

3. Try to play the bag:

   ros2 bag play compressed_bag

@zmichaels11 what changed in between that you closed this ticket? Same for #413

[zmichaels11]

@Karsten1987 our team reviewed the work done and verified that the problem was solved.
@emersonknapp can you add a comment here explaining why?

This was resolved with #417 but our internal process had blocked actually closing the issue pending team review/demo. We're going to be modifying that process though. Sorry for any confusion.
