I'm getting this assertion failure when setting a breakpoint on a C++
member function. What does that mean? This failure exists since the
function was introduced. When I remove the assertion I don't see
anything wrong happening.
Andreas.

This means that GDB found the symbol you requested, at some address, X,
and associated with file:file F:L. Then, we find all addresses {Y} corresponding
to F:L. The assert means that X does not belong to the set of addresses {Y}.
This should not happen generally -- do you have a small reproducible example?

No, sorry, I saw this while debugging a KDE program. When I remove the
assertion I get this output (the function starts with an inlined QString
constructor):
