besc added a comment. I found a crash when applying this patch to 3.9.1 final (source archives from http://llvm.org/releases/download.html#3.9.1) and compiling LLVM/Clang with MinGW-w64 GCC 6.2.0 or MSVC 2015. Clang-format sometimes crashes with input from stdin, output to stdout and a command line like this:
clang-format.exe -style=file -assume-filename=C:/path/to/file.hpp I’m not familiar with the code base, so these are just my observations from a user’s point of view. From what I found the problem could be linked to the first slash/backslash in an absolute path: Crash - C:/path/to/file.hpp - C:/path\to\file.hpp - /path/to/file.hpp - /path\to\file.hpp Works - Backslashes only always work. - C:\path/to/file.hpp - \path/to/file.hpp - path/to/file.hpp - path/to\file.hpp Header file (.hpp) or source file (.cpp) does not make a difference.
