[Gdal-dev] GDAL C# bindings freezing problem

[Ben Greene]

Hi,
 
I've been trying to modify an existing program to be able to read the georeferencing and image data from geotiffs using GDAL.  The program is written in VB.Net, but for my initial attempt I wrote a library in C#, and used that as a go-between.  I was having frequent crashing issues when the program hit the functions that load the image, so I switched to another library for the image loading stuff (I was also having trouble with indexed images, and it crashed much more often with certain images).
 
I was still having the crashing problems, so I removed the references to my library, and everything worked.  I tried converting my code to VB and integrating it into the original program, but I'm still having the same issue.
 
When the program crashes, it just freezes, taking the debugger with it (when I try to break, the environment freezes.  I then have to kill the process, and the debugger unfreezes).  This happens at different lines throughout the program, and for some images very occasionally (one in 20 executions maybe) won't happen, but with others will work most of the time.  There doesn't seem to be any pattern to the compression used, but larger images seem to be slightly more likley to crash.
 
Has anyone else had similar problems?
 
Cheers
