        <pre>I have downloaded and installed clang on windows 10 from
<a href="http://releases.llvm.org/download.html">http://releases.llvm.org/download.html</a> and mingw from
<a href="https://sourceforge.net/projects/mingw-w64/">https://sourceforge.net/projects/mingw-w64/</a>

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</pre>
