I'm guessing the problem has nothing to do with derived classes, it's
that identifiers in the capture-list must be local variables or 'this'
so to capture a member you must capture 'this'

So you probably want:

[this]() -> void
{
    variable->memfunc();
}

GCC 4.6 accepted incalid captures but that was probably changed by the
fix for http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50736
