Symptoms

There is a constant reproducible crash to desktop when launching the game. Using various launch options the game always exits to destop reliably between immediately to 20 minutes from this error: wine: Call from 00006FFFFFC1CF07 to unimplemented function KERNEL32.dll.HeapSummary, aborting

Reproduction

This CTD happens when using no launch options, with simple launch options like gamemoderun and mangohud, it happens with X11 session on gnome and plasma, it happens on wayland with gnome and plasma, and it happens when using gamescope launch options.

This is a new error when running the game with proton, since the latest patch as of yesterday, Sept 17th, patch 1.001.001

Hello @pr0nstache, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/7486#issuecomment-2359463646.

This issue is still actively occurring on Proton Experimental 10.0-20260210 (Feb 2026) with NVIDIA driver 590.48.01 (RTX 5090), Ubuntu 24.04, kernel 6.17.

The crash is 100% reproducible under heap pressure — specifically Helldivers 2 Eradicate missions on Terminid maps, where hundreds of enemy spawns cause the game to call HeapSummary for heap diagnostics.

Journal logs showing 4 consecutive crashes in one session:

Feb 25 22:54:17 wine: Call from 00006FFFFFC0D157 to unimplemented function KERNEL32.dll.HeapSummary, aborting
Feb 25 22:55:22 wine: Call from 00006FFFFFC0D157 to unimplemented function KERNEL32.dll.HeapSummary, aborting
Feb 25 22:56:54 wine: Call from 00006FFFFFC0D157 to unimplemented function KERNEL32.dll.HeapSummary, aborting
Feb 25 22:58:23 wine: Call from 00006FFFFFC0D157 to unimplemented function KERNEL32.dll.HeapSummary, aborting

The game runs fine for 60-75 minutes on other mission types, then crashes deterministically the moment heap pressure peaks on Eradicate Terminid. Relaunching into the same in-progress mission crashes within ~1 minute because the enemy count is already at maximum.

A trivial 6-byte binary patch to kernelbase.dll (mov eax, 1; ret replacing the stub) resolves this completely. The proper implementation exists as Wine MR !8237 (https://gitlab.winehq.org/wine/wine/-/merge_requests/8237) but has been unmerged since June 2025.
