Public bug reported:
Seen with g++ (Ubuntu/Linaro 4.9.2-10ubuntu13) 4.9.2 on Ubuntu 15.04
when compiling MySQL 5.7.7-rc.
It compiles if I set -O1 for btr0btr.cc and -O0 for gis0sea.cc.
See bug #1353729 for a similar case that has been fixed.
~/mysql-5.7.7-rc/build$ cmake .. -DWITH_BOOST=~/boost ### Boost 1.57 headers,
unpack the tarball in ~/boost
~/mysql-5.7.7-rc/build$ make VERBOSE=1 -i
