            Bug ID: 30353
           Summary: unwanted line break after variable definition using
                    macro in type name
           Product: clang
           Version: 3.8
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Formatter
          Assignee: unassignedclangbugs at nondot.org
          Reporter: michael+llvm at stapelberg.de

    Classification: Unclassified

My input file is:

struct foo {
    int bar;
    TAILQ_ENTRY(a) bleh;
};

The resulting output is:

$ clang-format --version
clang-format version 3.8.0 (tags/RELEASE_380/final)

$ clang-format -style="{BasedOnStyle: google, ColumnLimit: 0}" input.c
struct foo {
  int bar;
  TAILQ_ENTRY(a)
  bleh;
};

The expected output is: no line break changes.

This used to work with clang-format 3.6 and changed with clang-format 3.7.

I’m using ColumnLimit: 0 to not limit line length (e.g. for function
definitions or string literals).

In case it’s in any way relevant, the project in question is
https://github.com/i3/i3

Could you please explain how I could achieve the intended behavior with
clang-format ≥ 3.7 in case this isn’t a bug? Thanks!
