    I'm using lldb-18 to debug my llvm build. When I try to call `F.viewCFG()` through debugger, lldb reports error:
"error: Execution was interrupted, reason: vfork.
The process has been returned to the state before expression evaluation.". Then the debugger basically stuck and only after I manually kill the lldb process, the CFG shows up in a new window. Here is a screenshot.

I tried the same with gdb-12, it can execute `viewCFG()`, open the external software and continue execution.
