lldb error - step over failed (could not create return address breakpoint)

[kglundgren]

Steps to reproduce:

Create a file hello.c with these contents:

#include <stdio.h>

int main()
{
    puts("Hello, world!");
}

Compile it with clang-cl like this: clang-cl hello.c /Zi /Od /Fe:hello.exe ...or with clang like this: clang hello.c -g -O0 -o hello.exe

Run LLDB: lldb hello.exe Put a breakpoint in main: b main Step using n until you reach the puts call. At that point the error will occur:

Process 19192 stopped
* thread #1, stop reason = step over failed (Could not create return address breakpoint.)
