2.2.10 fails on Ubuntu 16 and 18

See original GitHub issue

Gah! if it’s not one failure it’s another. Now 2.2.10, which fixed the dotnet build failure (but apparently only on Windows) fails on Ubuntu 16 and 18 with this:

Repro steps

On a Linux machine (or Linux on Windows) such as Ubuntu 16, 18, or Linux Mint 19:

git clone https://github.com/aarnott/nerdbank.streams
cd nerdbank.streams/src/Nerdbank.Streams
git checkout fixLinuxBuild2
LD_DEBUG=versions dotnet build

The output is long, but includes this error:

      2512:	/usr/share/dotnet/shared/Microsoft.NETCore.App/2.1.3/System.Globalization.Native.so: error: symbol lookup error: undefined symbol: GlobalizationNative_ToAsciiW (fatal)

Interesting. I wonder if this is a similar issue to what using UniqueId.UniqueIdentifier as the MarshalCookie is intending to solve: https://github.com/libgit2/libgit2sharp/blob/master/LibGit2Sharp/Core/NativeMethods.cs#L100

I’d have to track down the original issues, but IIRC that was added to work around a custom marshaling bug when two different versions of LibGit2Sharp were loaded.

In this case, you’ve still got two different copies of the assembly loaded, but they share the same MarshalCookie, so things are getting messed up.

I just forcibly renamed it to remove the prefix. It still loaded on demand, but p/invoke did not find it, as you predicted.

Yeah, I really wish it worked properly on linux as well, because then I’d be able to finish https://github.com/libgit2/libgit2sharp/pull/1571 and handle all of this internally for you.
