I assume it's a Windows-only issue, someone can try on another OS?
And does it happen on AMD GPUs?

I'm using NVIDIA GeForce GT 710.
Windows 10 latest forced updates. Version 10.0.19042.1288

MAME - latest git.

No crashes.

Could not replicate this on AMD

No crash
- Win10 Radeon RX580 (fresh win10 install (updated), 237 release binary, latest AMD drivers)
- Ubuntu 20.04 Radeon RX580 (compiled 237 dirty)

Run with:
mame -waitvsync -skip_gameinfo -window -video bgfx -bgfx_backend vulkan -bgfx_debug -bgfx_screen_chains %CHAIN% -rompath %ROMPATH% %ROM%

where CHAIN was both auto and crt-geom-deluxe and ROM was 1942 and pacman

no crash reports should probably be rerun with -bgfx_debug to confirm vulkan backend is in use and mame has not fallen back to d3d which I noted happened on a non vulkan gpu and no crash.

Can confirm crash :
AMD 2400g/Nvidia gtx960/16gb/win10

-bgfx_debug shows using vulkan and gtx960

I can get it to happen on Win10 with NVIDIA GeForce, but not reliably – sometimes I have to resize the window lots of times before it happens. The -waitvsync is a red herring, it can happen with -nowaitvsync as well. It's just somewhat random whether it will happen on any given resize.

Happens here on Debian 11 Linux. Though I am using local compiled subtarget arcade.
#>./sdlmamearcade64.V0237.Mainline pongf -video bgfx -bgfx_backend vulkan -bgfx_debug -window -skip_gameinfo

I can't resize very much before it chokes or seg faults.
V0228 Seems to choke as well but doesn't seg fault.

Interestingly I left -skip_gameinfo on and noticed it was mirrored. (Uploaded).
And I also got ALOT of warnings with -verbose enabled
(Mame 0228 does not display these warnings nor was it mirrored)
Starting Pong (Rev E) [TTL]
Warning: Attempting to retrieve a nonexistent target 'temp' for screen 0
Warning: Attempting to retrieve a nonexistent target 'temp' for screen 0

Note:Never used bgfx or vulcan before so not sure all is as should be on this machine.

I wonder if disabling BGFX_CONFIG_MULTITHREADED might give a better trace.

is configured in mame.ini or when compiling ?

It is a compilation define which needs to be the bgfx build files.

I am having issues reproducing this now. I have made no changes to the code.

Using build with BGFX_CONFIG_MULTITHREADED=0 I sometimes see the following when exiting MAME:
X Error of failed request:  BadDrawable (invalid Pixmap or Window parameter)
  Major opcode of failed request:  72 (X_PutImage)
  Resource id in failed request:  0x380002
  Serial number of failed request:  4642
  Current serial number in output stream:  4654

Thanks sharing the compile setting.

Tested in Linux Ubuntu 20.04 using an "old" Radeon HD 3000 (760G .... before 2010) using kernel drivers and Mesa current version.
Not any crashes in moment when trying resize window.

Perhaps the bug is related with windows and Nvidia drivers ?
