Domain changed to fastdl because that's what I found on the MongoDB website.

Patch removed because it is included in the source.

This version segfaults on darwin https://gist.github.com/LnL7/07a14189e4fa059d56e33210f239d686

I'm still getting the segfault on darwin after the update. I suggest forking the package in two where mongodb_3_2 is the default and mongodb_3_4 the new one that only works on linux.

Maybe https://github.com/Homebrew/homebrew-core/blob/master/Formula/mongodb.rb will give us some hints like the requirement on cxx11

[disassembler]

@zimbatm @LnL7 @copumpkin can we test this on darwin again and see if it still segfaults?

[LnL7]

This might have been fixed by #27598, I don't remember if I tested this afterwards.

Merged just now when mongodb needs another patch due to a std::string change in pcre-8.41. I'll apply it shortly.

Nice, I was about to submit https://github.com/NixOS/nixpkgs/compare/master...pbogdan:mongodb-fix-build?expand=1 but didn't realise an upstream patch was available.
