Package: clang Version: 1:3.5-26 An update to the "clang" package in the last month breaks clang++ when using -std=gnu++1y and -g. The following error begins to appear all over:
error: debug information for auto is not yet supported Unfortunately, the error has no line number, making it hard to narrow down the cause. Certainly many uses of "auto" work just fine. I attempted a binary search commenting out code, but this didn't seem to help: it seemed that any one instance of the error is caused by many different lines in the code. You can observe the problem by attempting to compile Cap'n Proto from source code (https://capnproto.org/capnproto-c++-0.5.3.tar.gz) with the following configure invocation: ./configure CXX=clang++ CXXFLAGS='-std=gnu++1y -g' The error only occurs in C++14 mode (e.g. -std=gnu++1y or -std=c++14), not in C++11 mode. The code compiles successfully in C++11 mode. The problem is not present in clang-3.6 nor clang-3.7 packages, only in clang and clang-3.5.
