I have a plugin code which is developed using Opentelemetry C++ where the code
is running fine on gcc version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) when i
deploy the same code in gcc 9.5.0 or 11.4 (Ubuntu 9.5.0-1ubuntu1~22.04)  the
plugin is generating following error.

terminate called after throwing an instance of '
std::bad_alloc'

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.
