memory sanitizer reports errors for simple example

[mkandulavm]

Hi

I am trying to integrate the given simple multiplication example into a project. I use the memory sanitizer by default and it is showing following info.

single_include/kompute/Kompute.hpp:1049:30: runtime error: member call on address 0x555559947500 which does not point to an object of type 'TensorT'
0x555559947500: note: object has invalid vptr

Please help on how to proceed.

Also, in debug mode I am getting a segmentation fault in manager.cpp at this line
this->mInstance->destroyDebugReportCallbackEXT(

why is this happening ?

Once I defined this , the problem got resolved
KOMPUTE_OPT_DISABLE_VK_DEBUG_LAYERS

thank you.

Nice - thank you for updating, it does seem like there is a raised warning from the debug layers so we'll have a look. Thank you for reporting

I'm getting a crash for this line aswell:

[Jun 28 2023 13:36:45] [debug] [/home/stephan/Development/bcenc-gpu/build/_deps/kompute-src/src/Manager.cpp:26] [VALIDATION]: Validation - Validation Error: [ UNASSIGNED-Threading-Info ] Object 0: handle = 0x12460c0, type = VK_OBJECT_TYPE_DEBUG_REPORT_CALLBACK_EXT; | MessageID = 0x5d6b67e2 | Couldn't find VkDebugReportCallbackEXT Object 0x12460c0. This should not happen and may indicate a bug in the application.

@feliwir thank you for reporting this issue, however it seems it's a different issue, quite a strange one.

Could you please create a new issue with the details on your versions of vulkan, etc (as per the issue creation tempalte)?

We'll close this issue as several debug layer issues have been resolved since the most recent version.
