[Playerstage-users] Null pointer bug in Player 3.x (readlog.cc) when subscribing to SONAR for playback - FIX attached -

[<jf...@ab...>]

Hi All,

I was trying to playback some simulations data using the player readlog
driver and every time I was subscribing to the sonar interface using
playervcr I got a segmentation fault. Well ... the reason was that the
allocation of memory for the poses of the sonar was missing.

To fix it, just add the following:

"geom->poses=(player_pose3d_t*)calloc(token_count, sizeof(player_pose3d_t));"

below line 2737 in the readlog.cc file, right after the assert statement
and it will work.

Cheers.
Juan
