[PATCH] D153674: [dataflow] Disallow implicit copy of Environment, use fork() instead

[Donát Nagy via Phabricator via cfe-commits]

donat.nagy added a comment.

I'm also using `gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0` (which supported according to the LLVM "Getting Started" page <https://llvm.org/docs/GettingStarted.html#getting-the-source-code-and-building-llvm>) and I see the same std::optional compilation errors. Please revert this commit or fix the build.
