[NikNik77771]

Description / Steps to reproduce the issue

1. Compile simple hello world application
   clang -g hello.c
2. lldb a.out
3. b main
4. run
5. n

(lldb) run
(ocess 396 launched: 'Z:\a1\cprojects\hello-world1\tests\a.exe' (x86_64)
1 location added to breakpoint 1
Process 396 stopped
* thread #1, stop reason = breakpoint 1.2
    frame #0: 0x00007ff707d71466 a.exe`main at hello-world.c:9:5
   6     */
   7    int main() {
   8        // Print "Hello, World!" to the console

Are you using the cygwin clang (clang --version)? That was only used for bootstrapping and isn't functional right now.

I also see those dwarf errors trying to use lldb to debug msys-2.0.dll. It wouldn't surprise me if there's some incompatibility between gcc's generated dwarf and lldb's reading of them.

Same result for compiling with gcc and clang.
