Bug ID: 40568
Summary: Unable to run windows binary compiled with
clang/lld/mingw
Product: lld
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: unassignedb...@nondot.org

I have downloaded and installed clang on windows 10 from
http://releases.llvm.org/download.html and mingw from
https://sourceforge.net/projects/mingw-w64/
I am trying to compile a very basic C program using clang/lld/mingw:
int main(int argc, char* argv[argc + 1])
{
return 0;
}
To compile I invoke:
clang.exe -target x86_64-windows-gnu -fuse-ld=lld.exe -g -gcodeview
-Wl,/debug,/pdb:example.pdb example.c -o example.exe
This creates an exe which faults on startup in mainCRTStartup
(__security_init_cookie to be precise).
However, running with default ld from binutils is successful:
clang.exe -target x86_64-windows-gnu example.c -o example.exe
In total I tried:
x86_64-8.1.0-posix-seh-rt_v6-rev0
x86_64-7.3.0-posix-seh-rt_v5-rev0
x86_64-8.1.0-win32-seh-rt_v6-rev0
x86_64-8.1.0-win32-sjlj-rt_v6-rev0
without any luck producing a functional program.
So I am wondering, is there something obvious I am doing wrong here?
EDIT: I have also tried with msys2 to no avail. Specifically:
pacman -S mingw-w64-x86_64-clang mingw-w64-x86_64-lld
