Hello, I am having a problem with exception handling for C++ on GNU PPC Tools (MPC8xx platform). When I call "throw" from "try" block in my test application to raise an exception the control goes in the following way and traps into "abort" on returning NULL from _Unwind_Find_FDE function. __cxa_throw __Unwind_RaiseException uw_init_context_1 uw_frame_state_for Unwind_Find_FDE ("seen_objects" and "unseen_objects" are NULL so return NULL) Am I missing any switch or initialization related to c++/exception handling? Any help will be highly appreciated.
