WINE_MONO_VERBOSE=2 crashes wine with "wine_dbg_output: debugstr buffer overflow ..."

[HinTak]

I think this is a new issue found when revisiting #41 after a few years. Now it crashes with:

wine_dbg_output: debugstr buffer overflow (contents: 'GEN  BB2: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25,

The overlong debug str is likely a side-effect from the fact that mixed-mode assemblies are still not processed correctly... It probably will go away if the assemblies work correctly under wine-mono.

This should be fixed in Wine 6.17 by https://source.winehq.org/git/wine.git/commit/20dc5f378ca70f15cfe28a87e8ebda6a10eeed6f
