d-bugmail puremagic.com https://issues.dlang.org/show_bug.cgi?id=24129 Issue ID: 24129 Summary: ImportC: cannot compile any non-trivial program with multiple translation units/files: fatal error LNK1179: invalid or corrupt file: duplicate COMDAT '__acrt_locale_get_ctype_array_value' Product: D Version: D2 Hardware: x86_64 OS: Windows Status: NEW Severity: critical Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: trnsz pobox.com fatal error LNK1179: invalid or corrupt file: duplicate COMDAT '__acrt_locale_get_ctype_array_value' with DMD64 on Windows - it seems things are NOT being properly inlined. This is likely a new problem with the current MSVC header, because almost any non-trivial program that ends up including ctypes.h (or many other haders) cannot be linked, so nearly nothing can be built with ImportC. Reproducer: DMD version: DMD64 D Compiler v2.105.0-dirty Copyright (C) 1999-2023 by The D Language Foundation, All Rights Reserved written by Walter Bright (NOTE: this is the DMD installer from the website, not sure why it reports as dirty - I did not build it myself). Windows 11 with MSVC Community edition.
