Compilation error with latest Roslyn #865
Description
The following code no longer compiles:
Compiler reports the following error:
corefx/System.Buffers/ArrayPoolTests.cs(44,21): error CS0019: Operator '==' cannot be applied to operands of type 'T' and 'default' [/Users/filipnavara/agent/_work/1/s/work/performance/src/benchmarks/micro/MicroBenchmarks.csproj]
This is caused by breaking change in the compiler (dotnet/roslyn#36492) that was previously leading to miscompiled code. Originally reported as dotnet/roslyn#38568, moving here.
