Interestingly, this is failing only for the wasm/highresource_aot jobs, and not the regular AOT ones.
- highresource_aot: runs some library tests, and run them on the build machine itself
- regular EAT/AOT: runs the tests on helix
Could it be using an older linker?

System.Text.RegularExpressions.Tests is high resource so that makes sense
radical commentedon Jul 9, 2022
System.Text.RegularExpressions.Testsisn't built in EAT, or AOT builds. Only in the highresource_aot .[wasm] Disable tests failing on HighResourceAOT job
