What platform are you running on?

One thought is to try this:

./autogen.sh
./configure
make clean
make bootstrap

and see whether that clears things up.

Gentoo / AMD64 / GLibc 2.16 / GCC 4.7.2 w/ hardened patches

Looks like -fno-pie solve the problem. In other case unexec failed at
dumping .data section (incorrect address)
