Never saw that one. I've noticed though the qemu build system doesn't rebuild code on cflags changes, and switching object files from -y to -m (which adds -fPIC to cflags) can cause build errors which go away when you rm -rf the build tree (or at least the subdirectory where I'm hacking on) and try again. > Asking because I don't recall ever seeing that on a clean build. Yea, that hints it is the same problem. HTH, Gerd
