[Bug 52131] wine-mono + RMS Express: HF Channel Selection Browser crashes

[WineHQ Bugzilla]

--- Comment #10 from Eric <eric.wheez at gmail.com> ---
Ok, so, the "WINE_MONO_TRACE=program" log seems to indicate the crash is
happening somewhere soon after
"RMS_Express.Propagation:GetPathQualityIndicesFast" is called and before the
program returns from that method (since we don't see that method returning).

The Improved dotNET Tracer (on Windows) log indicates that
PropagationPrediction.dll is called for the first time right after
RMS_Express.Propagation:GetPathQualityIndicesFast , so I'm guessing that
RMS_Express.Propagation:GetPathQualityIndicesFast calls methods within
PropagationPrediction.dll.

To trace methods within PropagationPrediction.dll, I ran
`WINE_MONO_TRACE=N:PropagationPrediction wine RMS\ Express.exe 2>&1 | tee
namespacepropagation1.log` and found that the crash happens right after leaving
PropagationPrediction.PredictionClass:CreateDVOACapQuery. The program enters
and leaves this method many other times previously without problems, however
(though this is the only instance when "RxLocations" Lat is only 3 digits and
the only instance when Lon is 5 digits?).

The backtrace does mention "dvoa", which looks like CreateDVOACapQuery(?)

I'll attach the namespace log and its corresponding backtrace too.

Other tidbits:
 - "DN06UB", is my "home gridsquare location", which approximately locates my
old apartment near Walla Walla, WA.
 - My home gridsquare seems to be compared with other another gridsquare
locations (probably winlink 'gateway' radio stations).
 - Right before the crash, "DN06UB" is compared with "OJ02UX" (which is
somewhere in Kajang, Malaysia and has that different-looking lat/long).
