exec_shield is one such feature, and newer kernels use something like,
uh, /proc/sys/vm/randomize_... (I don't remember the particular name
right now and don't have a Fedora active).  The latter loaded
executables' memory segments into randomized locations to make buffer
overflow attacks less predictable.

exec_shield could be gotten around with using
setarch i386 make
and configure does that already IIRC.  But the address space
randomization was prohibiting the dumping even with the setarch
command.
