#45 Crash while searching for points with same x,y coordinates

[Eder Moreira]

I had problem running the file http://www.sendspace.com/file/n4991o with the new version of MCC number 1.0rc4. It crashes in the begin of the process.
To the same file I tried to run the MCC old version number 1.0rc1 and ran successfully.

Parameters:
mcc-lidar -s 4.0 -t .3 E:\data1.las E:\datamcc.las

Thanks,
Eder.

• summary changed from Old version of MCC working and the new version do not to Crash while searching for points with same x,y coordinates

I initially thought this was a duplicate of the silent crash reported in ticket #36. But I was able to reproduce the crash on OS X:

> mcc-lidar -s 4.0 -t .3 data1.las output.las
Reading 2,915,761 points from 'data1.las' ...
  min X Y : 549291.99 5206500
  max X Y : 553150.99 5210254.99
Searching for points with the same x,y coordinates...

The output indicates that this error occurs at a different place.

• status changed from new to closed
• resolution set to fixed
• milestone set to 1.0 - final

The crash was due to a bug in the code that handles the vertical stacks of points (i.e., those that have the same X,Y coordinates). It only happens when the last point in the input file happens to be in one such stack.

Fixed in revision r184.
