            Bug ID: 103851
           Summary: Intel Vulkan driver seg-faulting in LunarG Layer
                    Validation Test
           Product: Mesa
           Version: 17.2
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Vulkan/intel
          Assignee: intel-3d-bugs at lists.freedesktop.org
          Reporter: marky at lunarg.com

Vulkan Installation Analyzer System output

System Information captured in via.html (attached).

The test "vk_layer_validation_tests" is intended to make sure that the
validation layers properly catch each error that we detect.  However, one of
the tests is triggering a seg fault.  This test is working on AMD Windows,
Nvidia Windows, Intel Windows, and Nvidia Linux, although I think it may be
showing a few errors on some of those.

Repo steps:

1) Make sure Mesa Vulkan is loaded/installed on your system
2) Clone the Vulkan-LoaderAndValidationLayers
3) Follow build instructions in BUILD.md
4) cd to <build_folder>/tests
5) Run ./vk_layer_validation_tests

Expected, complete the test without crashing, ideally with no errors.  Actual
results, seg faults running "CreatePipeline64BitAttributesPositive" sub-test.

[ RUN      ] VkPositiveLayerTest.CreatePipeline64BitAttributesPositive
Segmentation fault (core dumped)

This has happened for a while, but I've been negligent in logging it.
Word of warning, there's also a test called "vk_loader_validation_tests", that
test runs fine, so make sure you run the "layer" version.
