<span>I'm trying to build a Net8 AOT project with trimming. I get "<strong>ERROR: Container build returned 125" </strong>at the end. I presume this is some sort of out of memory message because if I disable trimming it builds. I have the build size set to 8x (also tried 16x) but it always fails.</span><span>I don't get this error building locally (32GB dev machine). </span><span>Is there a trick for running AOT trimming on Bitbucket?</span>
