--- Comment #2 from Veeraraghavan Sekar <svraghavan7 at gmail dot com> --- Okay thanks @Jonathan for your comments. Code works during some examples with GCC11.4 but fails some case with above shared error. You have common reason on what cause _Unwind_Resume and _Unwind_RaiseException_Phase2? Does D_GLIBCXX_USE_CXX11_ABI flag will have impact? Since I am less experienced in C++ please bear with me on type of questions.
