double free or corruption #6
Comments
|
I should mention that the example file opens fine, and three other bags seem to work alright. |
|
May have nothing to do with matlab_rosbag? http://answers.ros.org/question/108956/cannot-convert-imu-messages-from-bagfile-to-csv-file/ |
Previously things were getting double freed when there were no embedded message definitions in the bag. Similarly, memory was getting lost when there were multiple messages in the bag. Fixes #6
|
(apologies for the delay, busy time of year). Thanks for the error report, bag, and link to answers; that helped me narrow it down pretty quickly. I agree message definitions are not embedded properly. matlab_rosbag now gives a (helpful?) error message when this happens. Can you download the below version and confirm the fix works? https://github.com/bcharrow/matlab_rosbag/releases/tag/v0.4 |
|
I'll be away from my lab for a few weeks unfortunately. :( I'll leave it on my to do list for you though.

Did you get a chance to verify this? https://github.com/bcharrow/matlab_rosbag/releases/tag/v0.4-rc.2 |
When trying to open the following bagfile:
https://www.dropbox.com/s/tie8svln73ii3ii/imu.bag
Matlab hangs with the following error in the terminal:
$ matlab
