--- Comment #6 from Sagawa sagawa.aki+winebugs@gmail.com --- Does it happen with Arch Linux's package? On my environment, the scan completed without the issue. I built up Arch Linux on my VirtualBox and tested its package, wine 5.13-1.
The scan also ran smoothly with git version, wine-5.13-268-gb7e51a1653, without my patch with gcc 10.1.0-2.
