[x86/Linux] Fix SIGSEGV on Debugger.Break() during debugging.submit/tizen_5.5_mobile_hotfix/20210923.022210tizen_5.5_mobile_hotfix
SIGSEGV occur in src/vm/i386/cgenx86.cpp `HelperMethodFrame::UpdateRegDisplay()` at line `pRD->pCurrentContext->Eip = pRD->ControlPC = m_MachState.GetRetAddr();`, since `pRD->pCurrentContext` is NULL.
The point of issue - wrong code block compilation in DebuggerWalkStack() in case of Linux x86.
