My system is Linux archlinux 4.15.8-1-ARCH #1 SMP PREEMPT Sat Mar 10 00:00:33
UTC 2018 x86_64 GNU/Linux.
My gpu is intel hd graphics 630.
I installed latest mesa from git (18.1.0_devel.100894.fcf267ba08)

When recording command buffer I get error:

Program received signal SIGBUS, Bus error.

alignment=alignment at entry=32) at vulkan/anv_allocator.c:913

I send push constants with matrix and color (80 bytes) for both stages. The
limit is 128 bytes so it should be fine. I get no validation output from
standard layer.
The function that creates secondary command buffer:
