Description Aron Budea 2019-12-22 02:46:19 UTC

This is an Intel i7-3520 CPU with a HD4000 iGP.
When starting an LO master build (6.5.0.0.alpha0+, ddd1d219beb74f55eefbccc3ab8a8883dd0b4b69 / Windows 7), it outputs the following, and then crashes:

warn:vcl.opengl:10404:11080:vcl/opengl/win/WinDeviceInfo.cxx:496: use :
vkEnumeratePhysicalDevices returned no supported devices.
warn:vcl.skia:10404:11080:vcl/skia/gdiimpl.cxx:269: cannot create Vulkan offscreen GPU surface, disabling Vulkan
Illegal instruction

I guess it's fine to move it to NEW

Comment 2 Luboš Luňák 2020-01-10 13:41:32 UTC

Can you please provide a backtrace? The 'illegal instruction' is strange, it should mean either miscompilation or some bad memory corruption.

Backtrace

Attaching backtrace. At this point VS is giving me this message:
"Unhandled exception at 0x000007FEBE9E0E6E (skialo.dll) in soffice.bin: 0xC000001D: Illegal Instruction."
