It did not matter in the past, but it matters now with new version of libstdc++ that came with gcc8. The OrcJITTests calls `std::make_shared`, which eventually calls `__shared_ptr` and that calls `std::_Sp_counted_ptr_inplace<...>::_M_get_deleter`. This `_M_get_deleter` takes a `std::type_info` parameter. If rtti is disabled, then some kind of fake type_info is passed instead. When the test is run, the `__shared_ptr` constructor from the OrcJITTests binary calls `std::_Sp_counted_ptr_inplace<...>::_M_get_deleter` from the libLLVM library. Each is compiled with different rtti, so they disagree on what the parameter means, because of this the `std::shared_ptr` is eventually created with nullptr inside. Later the test crashes when trying to use it. AFAIK mixing rtti and non-rtti code is not good idea. LibLLVM is built without rtti by default, but they recommend to turn it on for packaging, which we do. The tests are always built without rtti - I think this is a bug in LLVM build system. -- You are receiving this mail because: You are on the CC list for the bug.
