Research direction

Start by reproducing mixed mode debugging with the interpreter and inspect coreclr/debug/ee/debugger.h around line 1404, where the invalid-address assertion is reported. Determine why addressToOffset receives an invalid address; done means the spurious assertions no longer appear while execution continues correctly.

Written by the indexing model from the issue text.

Description

area-CodeGen-Interpreter-coreclr

When using mixed mode debugging with the interpreter, you'll get a lot of spurious assertions that look like this:

Debug Assertion Failed!

Program: ...s\tests\coreclr\windows.x64.Debug\Tests\Core_Root\coreclr.dll
File: Z:\runtime\src\coreclr\debug\ee\debugger.h
Line: 1404

Expression: !"addressToOffset called with invalid address"

If you ignore them execution will continue and everything works. Probably not important but wanted to log it anyway.
