The OOM is not limited to `guessLanguage()`. (See 119a72866f0e for an improvement to the performance of `guessLanguage()`.) It occurs even if you rename the header files to .cpp files and clang-format the renamed files directly. I'm with @mydeveloperday on this and believe a more general solution is needed. https://github.com/llvm/llvm-project/pull/78925 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
