When I use o-llvm compiler where -mllvm -bcf -mllvm -bcf_loop=1 -mllvm -bcf_prob=20 param, there is no response, even one day. Similarly, I hava integrated with XCode 9.2, but there are exceptions when build. The Exceptions:

  1. parser at end of file
  2. Per-module optimization passes
  3. Running pass 'CallGraph Pass Manager' on module '/Users/i-mac/Files/lhp/wzqqp_ios/frameworks/runtime-src/Classes/LuaAssert/AESEncrypt.cpp'.
  4. Running pass 'Bit-Tracking Dead Code Elimination' on function '@_ZNSt3120throw_length_errorEPKc' clang-4.0: error: unable to execute command: Segmentation fault: 11 clang-4.0: error: clang frontend command failed due to signal (use -v to see invocation) Obfuscator-LLVM clang version 4.0.1 (based on Obfuscator-LLVM 4.0.1) Target: arm-apple-darwin16.7.0 Thread model: posix InstalledDir: /Users/i-mac/Files/lhp/obfuscator/build/bin clang-4.0: note: diagnostic msg: PLEASE submit a bug report to http://o-llvm.org and include the crash backtrace, preprocessed source, and associated run script. clang-4.0: note: diagnostic msg:

Is there any way to fix it ?

For completeness, it seems the patch is this one: https://github.com/obfuscator-llvm/obfuscator/pull/76

At least, it worked for me.
