There is a need for the -fuse-cxa-atexit option on glibc, since g++ will never register global dtors with atexit; it will only register them with __cxa_atexit (if flag_use_cxa_atexit is true). It is easy to demonstrate that the compiler does not work correctly if -fno-use-cxa-atexit is used. Regards, Martin -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
