Here is the code-block from rosegarden that is failing in
src/document/RosegardenGUIDoc.cpp (line 2147 and 2152 designated with '*'):

*    for (RecordingSegmentMap::iterator i = m_recordMIDISegments.begin();
         i != m_recordMIDISegments.end();
         ++i) {

        Segment *s = i->second;
*        Segment::iterator i = s->begin();

        if (i == s->end() || !(*i)->isa(Clef::EventType)) continue;

        if ((*i)->getAbsoluteTime() < meaningfulBarStart) {
            Event *e = new Event(**i, meaningfulBarStart);
            s->erase(i);
            s->insert(e);
        }


I see the designations:

(1) RecordingSegmentMap::iterator i = m_recordMIDISegments.begin()
(2) Segment::iterator i = s->begin();

  How is the compiler seeing ' RecordingSegmentMap::' and 'Segment::' as the
same thing?

  More importantly, how to fix it?

  This is all withing the scope of:

2087  void
2088  RosegardenGUIDoc::stopRecordingMidi()
2089  {
...
2229  }

  Grepping it looks like it is declared a number of times:

archangel:/dat_e/tmp/rosegarden/src/document> grep -En 'Segment[A-Za-z]*::'
RosegardenGUIDoc.cpp
<snip>
2099:    std::vector<RecordingSegmentMap::iterator> toErase;
2101:    for (RecordingSegmentMap::iterator i = m_recordMIDISegments.begin();
2109:        for (Segment::iterator i = s->begin(); i != s->end(); ++i) {
2147:    for (RecordingSegmentMap::iterator i = m_recordMIDISegments.begin();
2152:        Segment::iterator i = s->begin();
2592:                             (Segment::Audio);
2710:    for (RecordingSegmentMap::iterator ri = m_recordAudioSegments.begin();

  What to do?
