Preparing for VulkanSceneGraph-1.1.8 - test result for Jetson Nano with Ubuntu 18.04

[reedev]

Hi Robert,

I ran the same list of examples on a Jetson. As you know, unfortunately, NVIDIA does not upgrade the OS on the Jetson...

Vulkan Instance Version: 1.2.70

NVIDIA Tegra X1 (nvgpu)

Bus error for the following examples, the rest seems to run ok:

vsgmultiviews
vsgviewer models/openstreetmap.vsgt
vsghelloworld
vsgrendertotexture models/openstreetmap.vsgt
vsgwindows models/openstreetmap.vsgt
vsgoffscreenshot models/openstreetmap.vsgt
vsgheadless models/openstreetmap.vsgt
vsgskybox models/openstreetmap.vsgt
vsgscreenshot models/openstreetmap.vsgt
vsgoverlay models/openstreetmap.vsgt
vsgallocator models/openstreetmap.vsgt
vsglog_mt
vsgtransform models/openstreetmap.vsgt
vsgpagedlod
vsgtextureprojection textures/VSGlogo.png
vsglayers models/openstreetmap.vsgt
vsgtiledatabase
vsgannotation models/openstreetmap.vsgt
vsgdynamicvertex models/openstreetmap.vsgt
vsgclip models/openstreetmap.vsgt
vsgcomputevertex
vsgdynamicviews
vsgdynamicload models/openstreetmap.vsgt
vsgdynamicwindows
vsginstrumentation models/openstreetmap.vsgt

Before I was using v1.1.3 but had not run all the examples, I will do that asap.

Do all these examples that fail, fail in the same way? You mention a bus error. Could you provide a stack trace for a couple of these failing examples as this might help shine a light to what might be going on.

For now, I checked 2 examples which don't rely on any data, and to me they don't seem (exactly) the same to me:

Of course, I can run each example via gdb. Please let me know how we can proceed.
