How do I do core dumps and backtraces?

[Kingoftherings]

I've been testing out Red Orchestra on Wine, and when I run it, it tells me that wineserver crashed and to run ulimit -c unlimited and try again.

So I did that, and tried, that time it didn't tell me wineserver crashed, but it did. I run wine again, and it says wineserver crashed last time, and to run this command:
gdb /usr/bin/../lib32/../bin/wineserver /tmp/.wine-1000/server-803-80a20a/core

So I run that, and it gives me this:

Am I doing this right? I'm guessing I need to recompile, glibc with debug symbols; I'm using Gentoo so that wouldn't be much of a problem, but it takes forever.

You need debug symbols for Wine, not glibc. And you already too late: http://bugs.winehq.org/show_bug.cgi?id=18900

Thanks. It'll still be good to know for the future.
