The problem reported above was the same up to and including qemu 0.15.0. Meanwhile I found this on the LinuxFromScratch (LFS) bug tracker:
"Glibc-2.14 causes segfaults in SDL", http://wiki.linuxfromscratch.org/lfs/ticket/2920 After applying their patch to GLIBC, qemu finally works again on the Pentium 4. As far as I am concerned, this bug report can now be closed. ** Bug watch added: Linux From Scratch Trac #2920 http://wiki.linuxfromscratch.org/lfs/ticket/2920 -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/722311 Title: Segmentation fault if started without -enable-kvm parameter Status in QEMU: New Bug description: I start qemu (Linux) from the same USB memory stick on several computers. Up to and including qemu 0.12.5, I could use or not use qemu's "-enable-kvm" command line parameter as appropriate for the hardware, and qemu would run. In contrast, qemu 0.13.0 and 0.14.0 segfault if started without "-enable-kvm". I get a black window appearing for fractions of a second, disappearing immediately, and then the error message "Segmentation fault". Hardware: Pentium 4, and Core 2 Duo. Command line: either "qemu" or "qemu -enable-kvm" (after manually loading the kvm-intel module on the Core 2 Duo). Reproducible: always.
