When developing Windows GUI applications I use:

freopen("CONIN$", "r", stdin);
freopen("CONOUT$", "w", stdout);
freopen("CONOUT$", "w", stderr);
so that the GUI app opens a console for writeln() output etc. I
assumed this should work for assert() messages as well. But it
seems it doesn't. If an assert fails, I don't see any output.
Is assert using something else? What's wrong about this
approach?
Are you sure the last call to freopen doesn't return NULL? You
are opening the same file twice and I'm not sure that works. Test
with `stderr.writeln("test")`.
