NX for 32bit programs is enabled by default now. Does it work with noexec32=off? If it's that then it won't work with PAE kernels on i386 and NX capable machines neither - i just changed the default to be the same as 32bit, but unlike 32bit all x86-64 kernels use PAE and many of the systems have NX. If it's not that don't know what it could be. I actually even used a simple wine program with a post rc2 kernel and it worked for me. So it isn't anything fundamental. Maybe some bad interaction with copy protection again, but I don't remember changing ptrace at all this time. > Alistair, if you can do a "git bisect" on this one, that would help. If noexec32=off doesn't help please do. If noexec32 helps then it's likely a wine bug for using the wrong protections. -Andi
