Given the "Normally it's an algorithm error ... wrong usin [sic] of 
class!" the right thing might also be to replace this with an assert. 
Presumably, digging into fdo#91988 will give you the necessary context 
to decide whether it is a programming error to reach that condition (so 
it should be an assert) or whether it is an exceptional state that can 
only be handled up the call stack (so it should be an exception) (or 
whether the current SAL_WARN+break is actually right after all, but 
which is probably unlikely).

In general, when visiting places in the code littered with exclamation 
marks (that are not negation operators), the best advice is to run 
screaming...
