But I do encounter crashes sometimes. I can't file a bug report on <a href="https://bugs.llvm.org/" _src="https://bugs.llvm.org/">https://bugs.llvm.org/</a> because I don't have an account. I sent an email to <a href="mailto:bugs-admin@lists.llvm.org" _src="mailto:bugs-admin@lists.llvm.org">bugs-admin@lists.llvm.org</a> for an account already but I haven't heard back. Meanwhile, can you take a look at the issue? I'm attaching the bug report files here -- the clang_error.log has the verbose output from clang and the other files are generated automatically by clang upon the crash. I'm using the above-mentioned commit 48aefa8877713616802d9c90b63f86fe50b9a101 from github mirror.
