There is no change in Wine that would have caused this. I seem to remember that this or a similar error was caused by threading problems in glibc in the past. Perhaps you upgraded glibc or the kernel on your system?
But when I checkout a cvs from the end of november, it runs.. when I checkout a current one it doesn't. I didn't upgrade glibc, nor the kernel. (I checked out and compiled a cvs from november just an hour ago, and it ran fine)
