segfault when reading gsf file with no cartesian coordinates

[rotu]

Describe the bug
mbinfo fails if the file contains only per-detection polar coordinates (TRAVEL_TIME_ARRAY, BEAM_ANGLE_ARRAY, BEAM_ANGLE_FORWARD_ARRAY) and not Cartesian coordinates (DEPTH_ARRAY, ACROSS_TRACK_ARRAY, ALONG_TRACK_ARRAY).

Opening the attached file with mbinfo crashes with a segfault. Note the segfault is observed with verbosity level -VVVV.

To Reproduce

mbinfo -F 121 -I 737_Public2.gsf -VVVV

737_Public.gsf.zip

Expected behavior

mbinfo should not crash. It should either tolerate only angular data or complain with a more semantic error.

Additional context
This code appears to be responsible. Note the access to depth, across_track, along_track without checking that these are populated:
