OK! I think I'm close:
I got better at using Improved dotNET Tracer for Windows (I found the "on/off"
button to specify when I want to start/stop tracing methods). I traced
On a Windows computer, I traced RMS Express calculating "SFI" when...
- input frequency is 55000 (which runs fine in wine-mono)
- input frequency is 54000 (crashes in wine-mono).
These methods pop up on Windows when input frequency is 54000 (but don't appear
when input frequency is 55000):

I bet the crash isn't from wine-mono calculating small value frequencies (in
PropagationPrediction.PredictionClass.CreateDVOACapQuery) any differently than
on Windows.
So, I think that both dotnet/Windows and wine-mono probably handle the
calculation the same but some exceptions get thrown by dvoa.dll as 'normal'
behavior in this case and dotnet somehow handles the exceptions, but wine-mono
doesn't know how to yet.
