I've updated gcc-core, gcc-g++, and libstdc++ to 7.3.0-2,
but the filesystem library still doesn't seem to be working:

#include <experimental/filesystem>
#include <iostream>
using namespace std::experimental;
int main() {
     filesystem::path p("expfs.cpp");
     std::cout << p.string() << " " << filesystem::exists(p) << "\n";
}

$ g++ -std=c++1z expfs.cpp -o expfs

/tmp/ccV1QAAo.o:expfs.cpp:(.text$_ZNSt12experimental10filesystem2v16existsERKNS1_4pathE[_ZNSt12experimental10filesystem2v16existsERKNS1_4pathE]+0x11):
