Which means that you are probably using "api.value.type variant".  Which does
not work properly with glr.cc.  That's the whole point of glr2.cc, on which
we are actively working currently.

Maybe in your case glr.cc is "almost sufficient".  I can't tell: I'm afraid
that once you get it to compile properly, it will run incorrectly.  I just
don't know.

Depending on your hurry, your options are:

1. don't store object, deal only with pointers
2. wait for glr2.cc to be ready for variants

Depending on what features you are depending upon, glr2.cc might already
be good enough for you.  I can wrap a tarball for you whenever you want.
But I don't foresee a release before at least February.

Cheers!
