A user is seeing this error compiling a generated c++ code from a schema in
GCC 7 that works in other versions (see
https://github.com/marbl/Mash/issues/47):
g++-7 -c -O3 -std=c++11 -Isrc -I/usr/include -I /usr/local//include -include
src/mash/memcpyLink.h -Wl,--wrap=memcpy -o src/mash/capnp/MinHash.capnp.o

Could this be related to the "stricter rules when using templates" in GCC 7
(https://gcc.gnu.org/gcc-7/porting_to.html)?
