Bug ID: 47226 Summary: Incorrect crash information displayed for unimplemented function stubs when 64-bit Wine builtins are cross-compiled in PE format (Mingw-w64, MS x64 calling convention) Product: Wine Version: 4.8 Hardware: x86-64 OS: Linux Status: NEW Severity: normal Priority: P2 Component: build-env Assignee: wine-bugs@winehq.org Reporter: focht@gmx.net Distribution: ---
Hello folks,
as it says. Example from bug 47220 which is dupe of bug 43546
https://web.archive.org/web/20190518075044/https://www.easyhdr.com/download/...
With Wine builtins cross-compiled in PE-format:
