one step further, I indeed forgot to rerun ldconfig, after I had build the libc++abi !
So now it links, and runs from within CB, and shell without LD_LIBRARY_PATH execution.
Well the "runs" ==> crashes
According to the debugger : in libcxxabi/src/cxa_exception.cpp
LIBCXXABI_NORETURN
void
__cxa_throw(void* thrown_object, std::type_info* tinfo, void (*dest)(void*))
{ /// <====================================== on this line stack ponter
during the call of : std::cout << "Hello world!" << std::endl;
just having a main that does return 0 ==> that doesn't crash
