How to reproduce

Compile a Visual Studio solution containing a high amount of DllExport powered projects on fast storage and CPU.

Reproduction of this is quite difficult and rare, unless stresstesting with unreasonable amounts of projects.
If the bug is reproduced, a compilation error is thrown, although very rarely:

What version and selected configuration ?

Version 1.6, latest at the time of writing.

Can you provide detailed log of your build ?

No detailed or diagnostics level (note: Now provided, see below) due to it slowing down the build process, making the issue not reproducible.

Workarounds

• Reduce parallel builds to 1 in Tools > Options > Build & Run.
• Simply build solution again.

Extra Notes:

The issue was first found and identified in this personal project of mine
