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}. A simple test is running
this:
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:
...
22793 cmake CALL linux_select(0x9,0x82d4630,0,0,0)
22793 cmake RET linux_select 1

22793 cmake RET linux_rt_sigreturn JUSTRETURN

Any ideas?
