It is impossible for FPC to catch a C++ exception on non-Windows  
platforms with FPC containing special code tying into the C++ run time  
(which it doesn't). What is possible is that if you have C++ code  
calling FPC code calling other C++ code, and the inner C++ code throws  
an exception, that it doesn't manage to crawl its way back to the  
outer C++ code because missing/incomplete/incorrect FPC dwarf-eh frame  
information.
