JNI Crash #5

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. When I make repeated calls to cvHaarDetectObjects(), it will eventually 
crash.

What is the expected output? What do you see instead?
I expect it to return a CvSeq object, but instead it will crash.

What version of the product are you using? On what operating system?
I am using the latest version of the product, and I have tried it on both 
Windows and MacOS X. 
While the actual output of the error on each machine is slightly different, the 
problem is in the 
same location.

Please provide any additional information below.
I have attached the code that I am using (FindFaces.java), which is rather 
straightforward. Also, I 
have included the error logs that were produced on the Windows machine as well 
as a mediocre 
one I generated from the Mac OS X machine. They are the same physical machine. 

This may be related strictly to JNI, but I wanted to post here before I went 
there.

It seems to crash trying to free a CallBack object somewhere.. the only thing I 
can
see is the "new JavaCvErrorCallback().redirectError();" line. Can you try to 
remove
this line and see what happens? Thanks

That appears to have fixed it. I will reopen if it begins happening again, but, 
for now, it appears to run perfectly.

Thank you very much.

Ok, that's good, but it should not happen with the error callback in place 
either...
What version of JNA are you using?

Hum, maybe it has been fixed with 3.2.5? Let me know if it causes the same 
issue with
3.2.5, and I will look further into it, thanks
