--- Comment #5 from zhonghao at pku dot org.cn --- (In reply to Jonathan Wakely from comment #4) > _Atomic is a C keyword, it is not part of C++. > > Clang++ accepts it as a non-standard extension.

Another bug report (https://bugs.llvm.org/show_bug.cgi?id=21835) also used the code. In particular, David Majnemer said that the following code, typedef _Atomic(int) T; T a = T(); is a reasonable test case. Please note that the use the the command, clang -fno-crash-diagnostics -std=c++11 -xc++ -c -emit-llvm, to trigger the bug. The command line indicates the programers of clang handle the code as a C++ code, instead of C code. I just want to improve the quality of both compilers. I do not understand why my reported bugs make you mad.
