Yeah, I get the same result with some apps. Interestingly, for me the
'GetThreadContext failure 5' error disappears when I run wine under
strace; that makes it look a lot like a race condition.

Try if it makes any difference for you:
strace -o /tmp/strace.log wine gdbserver.exe localhost:60000 epiar.exe

Also, http://bugs.winehq.org/show_bug.cgi?id=23246 mentions a
GetThreadContext failure that was supposedly fixed in wine 1.3.20, but
upgrading to wine 1.3.20 doesn't appear to make any difference here. No
idea if these problems might be related or not.

(For what it's worth, the gdb.exe from the same mingw32-gdb package
works fine under Windows here.)
