the following error appears when trying to compile using the flag -fsanitize=signed-integer-overflow

/usr/bin/ld: unrecognized option '--push-state--no-as-needed'
/usr/bin/ld: use the --help option for usage information

For me this worked:
sudo apt-add-repository "deb trusty main"
sudo apt-get update
sudo apt-get install gcc-5 g++-5
