The two API tests I converted to use yaml2macho-core were failing on windows. I was writing the output corefile with fopen(filename, "w"), and it turns out there was some newline conversion happening on Windows if a linefeed character was present. Charles Zablit helped to identify the issue and confirm the fix. Re-enabling the two tests on all platforms. https://github.com/llvm/llvm-project/pull/153911
