Hi fellow developer
I'm currently working on a strategic game addon, for the upcoming danish
title "Heroes & Generals". We use a CATiledLayer to update and render the
tiles of a "google maps" alike european WW2 map, but when rendering objects
for all the european cities, I get a SIGSEGV error, that i unfortunately
cannot solve ...
The error happends when trying to render a string:
test.DrawString(titleRect, UIFont.FromName("FetteEngDOT", fontSize),
UILineBreakMode.MiddleTruncation, UITextAlignment.Center);
I debug the values of titleRect and the test string itself, and everything
seems okay.
(debug: test = Cmd_Odense_US (titleRect:
{X=402,4781,Y=165,4276,Width=1,484375,Height=0,390625}
The stacktrace i get is this :

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
I really, really hope that someone to help pointing me in the right
direction ...
Thanks in advance,
