In my playing with MusicXML importing, I'm getting a segfault with my
last set of changes when I import a specific file from the MusicXML test
suite. This isn't happening every time, but usualy at least once per
2-3 loads of the file. The file itself is testing microtone imports, so
it *appears* to be linked to inserting microtone accidentals.
Microtones are already defined in Rosegarden; they're the following
constants:
Accidentals::ThreeQuarterFlat
Accidentals::QuarterFlat
Accidentals::QuarterSharp
Accidentals::ThreeQuarterSharp
Although they're defined, they don't get mapped to anything in the
rendering.
I reran Rosegarden in gdb to try to get a bit more information. Here is
the last of the trace output (having purged the 3 million Jack
warnings/errors/etc) and the backtrace.

[snip]
There's another 20 levels of backtrace but I think everyone will have an
idea of where we are now :-)
Anyway, looking at Composition::ReferenceSegment::find() I see
Composition::ReferenceSegment::find(Event *e)
{
return std::lower_bound
(begin(), end(), e, ReferenceSegmentEventCmp());
}
And here I really hope someone can suggest what's gone wrong without me
having go into the standard library and work through the logic.
Ideas?
(Note, the relevant import code is in the trunk under src/doc/io/).
