Debug Assertion Failed in File "xtree"
This error has occurred to me while running various JOCL samples and my own code. I've deleted the lines that did the assertion, but the error still persisted afterwards. I have also restarted my computer after deleting the lines, and the same error occurred after restart. After uninstalling Visual Studio 2019 and thus all of the include files of MSCV including xtree, running the program causes this error. I wonder if the problem is somehow related to Eclipse? It is important to note that the kernel seems to run okay; its just this annoying error message pops up whenever I run the host program.
(And once more: Sorry for the delay...)
This is not good... it looks like a basic, conceptual error of how a map is used at a certain point in the native code. I have to admit that I usually don't compile the DLL in debug mode, but I should definitely do this to catch more possible bugs.
I'll have to take a closer look at this, maybe together with the update to OpenCL 3.0. Thanks for the report.
Here's a look at the log file created when you press retry on the dialog above.
A fatal error has been detected by the Java Runtime Environment:

Here's my Java class that produced the error; the code has some fluff in it, sorry.
Thanks again, I'll have to allocate some time to try this out. I think it is due to a wrong usage of iterators in https://github.com/gpu/JOCLCommon/blob/master/src/main/native/CLJNIUtils.cpp#L792 (and a first guess would be that the erase call might be the culprit here, "invalidating" the iterator - so it might be just a matter of swapping two lines). But first, I'll have to try out whether I can reporoduce this in debug mode.
Hello Marco, I was wondering how you deduced this conclusion. Was it from past experience with the JOCL you created, the log file, or testing you have already done? I am just trying to follow your thought process to learn something possibly. I already created an executable file from launch4j to debug the dll with, but I have not found any culprit yet. I have been busy with schoolwork and my girl. I have not looked in CLJNIUtils.cpp yet, but its true the JNI naming conventions are giving me a headache. I guess you get used to it after a while -- like the Matrix.
Until now, it was only a guess, but ... the search space should be small: I think this is the only place where I'm using a value-initialized iterator at all.
There's not much necessity to use actual C++-features in JOCL. In the end, OpenCL is plainly C-based. But the callbacks that may be associated with a CL context have to be maintained somehow, The CallbackInfo essentially stores everything that is required to call (back) the Java function from C. This has to be cleaned up then the context is destroyed. I thought that a map from the cl_context values to the CallbackInfo values might make sense there.
