Ah, Fedora...

The following entry from etc/PROBLEMS should help you:

    * Segfault on GNU/Linux using certain recent versions of the Linux kernel.

    With certain recent Linux kernels (like the one of Redhat Fedora Core
    1), the new "Exec-shield" functionality is enabled by default, which
    creates a different memory layout that breaks the emacs dumper.

    You can check the Exec-shield state like this:

	cat /proc/sys/kernel/exec-shield

    It returns 1 or 2 when Exec-shield is enabled, 0 otherwise.  Please
    read your system documentation for more details on Exec-shield and
    associated commands.

    When Exec-shield is enabled, building Emacs will segfault during the
    execution of this command:

    temacs --batch --load loadup [dump|bootstrap]

    To work around this problem, it is necessary to temporarily disable
    Exec-shield while building Emacs, using the `setarch' command like
    this:

	setarch i386 ./configure <configure parameters>
	setarch i386 make <make parameters>

(It is always advisable to look in PROBLEMS for relevant entries if
Emacs fails to build or crashes too frequently.)
