Do you have any plans to reorganize wineconsole a bit so that you don't need allocate a bitmap as big as the entire buffer, but rather one as big as the displayed screen only? This way we can have 3000-5000 line scroll buffers (as I have in my konsole, rxvt, xterm, etc.)
that's somewhere way deep in my todo list... as of today you can use the (n)curses backend that does what you need (this means, for the debugger, to start it before a crash occurs) A+
except that I haven't commited the code for that yet :-( A+
