Falcon 4 BMS 4.34u2 crashes when loading 3D world (Acces violation @creation of OffScreen texture or RTT object)

[XenoPL]

Falcon 4 BMS 4.34 mod ran under wine-nine crashes during mission load screen.

There are two variants of crash message:

Falcon BMS.exe caused an EXCEPTION_ACCESS_VIOLATION in: 000000000455F3A9 Falcon BMS.exe, ImageBuffer::SetupAsOffScreenPlain()+377 byte(s) Exception handler called in UnhandledExceptionHandler. Write to location 0000000000000003 caused an access violation. Bytes at CS:RIP: C7 04 25 03 00 00 00 03 00 00 00 4C 8D 9C 24 90

or:

Crash screenshot:

System specs: Hardware: CPU: Intel Core2Duo E8500 @3.16GHz (stock) , m.b: GA-P35-DSR3, RAM: 8GB 1333MHz DDR3, GFX: RadeonHD 6870 1GB VRAM. OS: Fedora 31 64bit, kernel 5.5.6, libdrm 2.4.100-1, mesa 19.2.8-1, DE/Windowanager Plasma/kwin_x11 5.17.5,Wine: wine 5.2-1, wine-nine 0.5.

Wine config: clean Windows 7 64-bit prefix, wine-nine enabled via nine GUI app, gfx tab:

• allow window decorations
• allow window manager manage windows
• enable virtual desktop 1920x1200 (max res of my display) Stagging tab:
• enable CSMT
• Enable EAX Wine windows are forced to run fullscreen.

Steps to reproduce:

• Launch BMS
• Select Tactical Engagement/training (crash also occures wih other game types, i've tried Dogfight and Instant Action)
• From the list of missions pick TR_BMS_02_Navigation then commit
• Click TakeOff button
• Crash occures when progress bar is somwhere between 60-80%

With wine-nine disabled mission loads just fine. Funny thing training mission 13 works with wine-nine enabled. I've askefd a guy from a BMS project for some hints but he couldn't tel much:

Sorry but I don't have much clue here. This is a simple texture handling function that is being called when the code requires to create a "Off screen" rendering. E.g a 3D cockpit RTT target. I don't know why it's failing but seem to me like some obvious API issues that somehow prevent such a off-screen render target to be created. Hard to tell without any more info or reproducing such issue locally (Which obviously cannot be done).

Could be another case of process runs out of address space. And it's been a while, any progress on your end?

Possibly fixed by https://github.com/iXit/Mesa-3D/commit/84c3b6e64c243a1908734bd611c868c99d7a12f3

Is this fixed now when using mesa v21.1.0-rc1 or later?
