Thanks for your response! I am sorry, I should have mentioned 0.48.4 and I wrote 0.48.3 by mistake. :(
I read about the usage of Tdragon compiler instead of the mingw64 compiler - I use rubenvb 4.7.2 (target x86_64-win64-mingw32) personal build which is very stable. Is it possible that this compiler will result in the error below? I can temporarily install an old compiler to test it out.
