           Summary: Problems with -funit-at-a-time and c++ io manipulators
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: optimization
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: poschmid at lbl dot gov
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu

The code t.C does not link when the optimization -funit-at-a-time is
enabled. Therefore at -O3 some of the iomanipulators are not available.

Environment:
System: Linux linux 2.4.20-4GB #1 Fri Jul 11 07:33:18 UTC 2003 i686 unknown unknown GNU/Linux
Architecture: i686

target: i686-pc-linux-gnu
configured with: ../gcc/configure --enable-threads=posix --enable-languages=c,c++,f77,objc --enable-__cxa_atexit --enable-debug

How-To-Repeat:
source code t.C
struct Filter {
    struct Retry {
    };
    virtual int result() {return 1;}
};

int main_loop(Filter *p) {
    try {
	return p->result();
    }
    catch(Filter::Retry &m) {
	return 2;
    }
}


int main() {
    main_loop(new Filter);
}
