>Description:
I have a build chroot based upon FC2--please do not shoot me--that had
worked in the past with RELENG_6 on an i386 box.  I moved to RELENG_7 on
an amd64 box.  For some reason, running cmake core dumps regardless if
it is my FC2 chroot or linux_base-fc{4,6}.

>How-To-Repeat:
mkdir -p test/build
mkdir -p test/src
echo "PROJECT(ARGH)" > test/src/CMakeLists.txt
cd test/build
cmake ../src

This results in:
-- Check for working C compiler: /usr/bin/gcc
[1]    22830 segmentation fault (core dumped) /home/sean/devel/chroots/fc2/usr/bin/cmake ..

The output from linux_kdump near the final gasp:
