The Problem

Some foundry tests behave differently when the project is compiled with the via-ir flag or without.

How to reproduce

git clone --recurse-submodules [email protected]:malteish/troubleWithFoundryAndYul.git to clone this repo
cd into the local copy of this repo
forge test -vv. This executes the one test and shows the corresponding output. The test passes, even though it should definitely fail. Read the test for more details.
FOUNDRY_PROFILE=noYUL forge test -vv. This compiles the project without the via-ir flag. The test fails, as expected.

Please notice there are at least 2 problems here, which are described in the test.
