What is the memory savings on the test case from the issue? It looks like you have a Mac build issue

Can't say exactly. It filled all available RAM (28Gb) of the virtual machine before the fix, but the routing was not completing so it was probably going to use more. Now it uses about 21GB (20Gb reported by the router). From the 1.5kk fills it reduces to about 700k. Of course, this after I add the SPACER flag in the macros that were being used in cells name FILLER*.

I cannot see what causes the MacOS build error. In the last public CI, there were 2 metric fails: https://jenkins.openroad.tools/blue/organizations/jenkins/OpenROAD-flow-scripts-All-Tests-Private/detail/secure-TR_FillMemOptimization/1/pipeline

@maliberty are those metric fails here acceptable? https://jenkins.openroad.tools/blue/organizations/jenkins/OpenROAD-flow-scripts-All-Tests-Private/detail/secure-TR_FillMemOptimization/1/pipeline
