Preprocessed file that crashes clang
When compiling with -Wdocumentaion a file with windows newlines (CRLF) clang
3.2 RC3 crashes on some warnings. The same file saved with unix line endings
does not crash clang. Tested on Windows using
clang+llvm-3.2rc3-i386-mingw32-EXPERIMENTAL.tar.bz2. Notice the ugly <U+000D>
in the warning message code fragment.
C:\llvmCore-3.2-rc3.install\bin>clang -Wdocumentation fails.c
fails.c:2:15: warning: empty paragraph passed to '\param' command
[-Wdocumentation]
* @param abc<U+000D>
~~~~~~~~~~~~~~~~~~^
fails.c:2:11: warning: parameter 'abc' not found in the function declaration
[-Wdocumentation]
* @param abc
^~~
fails.c:2:11: note: did you mean 'qwerty'?
