From 754ab803b8dc659e3645d369d1b5d6d2f97be29e Mon Sep 17 00:00:00 2001 From: Andy Yankovsky Date: Mon, 1 Feb 2021 12:25:53 +0100 Subject: [lldb] Use current execution context in SBDebugger Use `GetSelectedExecutionContext()` instead of `GetCommandInterpreter().GetExecutionContext()` in `SBDebugger::GetInternalVariableValue/SBDebugger::SetInternalVariable`. The execution context in the command interpreter might be empty, if no commands has been executed yet (it is updated only when handling commands or completions -- e.g. https://github.com/llvm/llvm-project/blob/main/lldb/source/Interpreter/CommandInterpreter.cpp#L1855).
