Description Fabian Maurer 2017-05-05 21:34:45 UTC

When running the Vulkan demo program vkcube, it fails on vkMapMemory. When skipping the check, it segfaults.
Note that this is a regression, it used to work with the same program.


System it was tested with:
- Arch Linux 64bit
- Linux 4.10.13, AMDGPU driver
- Mesa 17.2.0-devel (git-a5f82db380) / Mesa 17.0.5
- Radeon R9 285

Demo program: https://github.com/krh/vkcube

Still present with 7bbcf3ac70.

vkcube is known broken, it allocates memory from a non-mappable memory type and then tries to map it.

Well, that was unexpected. Thanks for explaining, can confirm it work fine with the samples from https://github.com/SaschaWillems/Vulkan !

Can you really claim it's "known broken" when nobody told the maintainer?
