[Bug]: LSAN reports leaks in ONNX frontend about openvino HOT 1 OPEN

Correction: I also changed openvino::protobuf_shutdown to "$<LINK_LIBRARY:WHOLE_ARCHIVE,openvino::protobuf_shutdown>" here https://github.com/openvinotoolkit/openvino/blob/releases/2024/0/cmake/developer_package/frontends/frontends.cmake#L204. Without it linker throws away protobuf_killer object. Maybe it is enough to declare it as extern "C" or explicitly set visibility instead, did not try it.

LINK_LIBRARY:WHOLE_ARCHIVE is pretty fresh, don't know what cmake version you target. It it is too new, it is possible to create a proxy library instead which has explicit -Wl,--whole-archive in its link options.

Note that whole-archive does not help by itself, I still needed to replace destructor function with global object.

My toolchain is LLVM 18, GCC 14 (stdlib provider), cmake 3.29, ninja 1.11 on Ubuntu 20.04

from openvino.
