Ok, I have just build the CellML DOM API from scratch, and done the same
with my COR view branch. From there, I did my usual testing which consists
of starting OpenCell, switch into the COR view, and then open one or several
CellML files at a time. From there, if OpenCell doesn't crash, I would just
close it and start over again. Anyway, I did that several times and
eventually, I did get OpenCell to crash, so though some object files might
have been out of date, it would seem that it is not the (whole) issue here.

For information, here is what bt in gdb gives me:

This points to the line I mentioned in my previous message, i.e.

nsCOMPtr<mathml_domIMathMLApplyElement> mma(do_QueryInterface(aMathML));
