--- Comment #3 from kugan at gcc dot gnu.org ---
I am not able to reproduce it.

This is my setup:

I had to initialise variables in gcc/ccmp.c to workaround uninitiated
variables.
I did ./contrib/download_prerequisites in source tree.

x86_64-pc-linux-gnu-gcc -v
Using built-in specs.
COLLECT_GCC=/home/kugan/test/install3/usr/local/bin/x86_64-pc-linux-gnu-gcc

Configured with: ../gcc/configure --enable-languages=c,c++ --enable-multilib
