JavaCV crashes during IplImage deallocation #182

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
--------------------------------------
Not reproducible! Happens only after a while using many cvLoadImage() calls (or 
IplImage.createFrom() calls), and has something to do with the Java Garbage 
Collector.

What is the expected output? What do you see instead?
-----------------------------------------------------
The process crashes, reporting:
======= Backtrace: =========
/lib/libc.so.6(+0x776d6)[0x7f86014dd6d6]

And sometimes other messages...

What version of the product are you using? On what operating system?
--------------------------------------------------------------------
Linux 2.6.35-31-generic #63-Ubuntu SMP Mon Nov 28 19:29:10 UTC 2011 x86_64 
GNU/Linux
OpenCV 2.3.1, JavaCV Revision: 212

Please provide any additional information below
-----------------------------------------------
Happens also after recompiling JavaCV on the targeted machine, but less 
frequently - thus recompiling helps, but doesn't solve the problem.

Could you also provide some sample code that almost certainly crashes? Even if 
it has to loop a million times? I'd like to try it here see if I can reproduce 
it, thanks

I've ran this a couple of times here on my machine and nothing happens:
        for (int i = 0; i < 100000; i++) {
            IplImage.createFrom(ImageIO.read(new File("/usr/share/opencv/samples/c/lena.jpg")));
            cvReleaseImage(cvLoadImage("/usr/share/opencv/samples/c/lena.jpg"));
            System.gc();
        }
If I cannot reproduce the problem, I won't be able to fix it...

Given the lack of feedback, I am guessing this issue has been resolved, but 
please let me know if this is not the case, thank you.
