Random crashes #3

I mentioned this earlier here: http://doc-ok.org/?p=432#comment-1362 . I'm still having this issue, and would be happy to assist in fixing it. I could also deliver data that causes these issues for me.

It seems like random crashes while using LidarViewer. I don't see a clear way to reproduce a crash.

I get either one of these errors on OS X 10.10:

Segmentation fault: 11

or

libc++abi.dylib: terminating with uncaught exception of type IO::File::Error: IO::StandardFile: Fatal error 22 while reading from file
Abort trap: 6

I have tried redoing the preprocessing steps, but this does not help. I installed LidarViewer through homebrew.

I have now installed Ubuntu 14.04 on the same machine to see if this issue is OS X specific. Unfortunately I experience similar crashes. Random freeze ups an errors such as:

terminate called after throwing an instance of 'IO::File::ReadError'
what():  IO::File::ReadError: Short read by 2086167744 bytes
Aborted (core dumped)```

or

Segmentation fault (core dumped)

Could it have to do something with the filesystem that stores the dataset? I have always used Apple HFS+ so far. Update: no, I tried copying a dataset to an ext4 partition, still crashes.

I processed a new dataset from LAS files this time (previous were ascii) to see whether this makes any difference. Unfortunately not. I did receive another error message:

libc++abi.dylib: terminating with uncaught exception of type IO::SeekableFile::SeekError: IO::SeekableFile: Failed seek to position -4275254697502569974

I again noticed that at first everything seemed fine. I was playing around for a good 15 minutes, before it crashed. But then with any immediate following attempts to use LidarViewer on this dataset it would always crash within a few seconds. Rebooting the computer does seems to help. I can't really explain this, but that is what I observe.

I'm a bit sad that I can't use this great software package. I can see that it is really well designed, and I think it has great potential if it were only more actively maintained.
