When linux shared object (compiled with tcc) calls some c++ function, that throws exception, application crashes.

Seems that std::terminate is called from __cxa_throw ().

Is this something expected? (if  "so" is compiled with llvm or gcc C compiler it works ok)

Behaviour of a C app which allows a C++ exception to propagate through it is UNDEFINED. So, yes, what you're seeing is, in a sense, expected.

C code has no way of handling an exception, and a C++ app which does not catch an exception crashes.
