[Qemu-devel] Lament: 0.6 breaks usermode

I am disappointed with the direction qemu has taken.

Up to 0.5.5, I had rather decent usermode functionality with qemu-i386
on linux/PPC: Acrobat reader, Firefox with flash, even Wine after a
fashion. I was happy.

With version 0.6 up to and including the most recent snapshot, it's
gone: lots of "free(): invalid pointer 0x....!" , segfaults and no
I had hoped the user mode stuff would get better not worse.

FYI, I use:

kernel 2.6.6-2mdk
gcc  3.4.1 
glibc 2.3.3

Also FYI, I got a compilation error in 0.6.0 due to an error in

It's still there in the latest snapshot.

If it's pointless, what's the point?
