Research direction

Start in CSharp.Tests.cs at OverrideVirtualWithString.VirtualTakesAndReturnsString. Reproduce the base-call case in a release build and compare it with debugging behavior, then trace the virtual function's returned string and surrounding memory handling. Done means the test continues to return the expected string in release as well as while debugging.

Written by the indexing model from the issue text.

Description

To reproduce, go to OverrideVirtualWithString.VirtualTakesAndReturnsString in CSharp.Tests.cs and replace the hard-coded value with a base call. The test will then continue working when debugging the test but fail in release. It's most probably a problem with the memory.
