Prevent clang-format from breaking a line at -> operator

The following file test.cpp

int func() {
   aaaaaaaaaaa = bbbbbbbb->cccccc(SomeNamespace::Function(dddddddd?"eeeeeeeee":"fffffffffff")).gggggggggg();
}

is formatted with clang-format in the following way (I tried different styles):

$ for s in LLVM Google Chromium Mozilla WebKit; do clang-format -style="{BasedOnStyle: $s, ColumnLimit: 80}" test.cpp; done
int func() {
  aaaaaaaaaaa = bbbbbbbb
                    ->cccccc(SomeNamespace::Function(dddddddd ? "eeeeeeeee"
                                                              : "fffffffffff"))
                    .gggggggggg();
}
int func() {
  aaaaaaaaaaa = bbbbbbbb
                    ->cccccc(SomeNamespace::Function(dddddddd ? "eeeeeeeee"
                                                              : "fffffffffff"))
                    .gggggggggg();
}
int func() {
  aaaaaaaaaaa = bbbbbbbb
                    ->cccccc(SomeNamespace::Function(dddddddd ? "eeeeeeeee"
                                                              : "fffffffffff"))
                    .gggggggggg();
}
int
func()
{
  aaaaaaaaaaa =
    bbbbbbbb
      ->cccccc(SomeNamespace::Function(dddddddd ? "eeeeeeeee" : "fffffffffff"))
      .gggggggggg();
}
int func()
{
    aaaaaaaaaaa = bbbbbbbb
                      ->cccccc(SomeNamespace::Function(
                          dddddddd ? "eeeeeeeee" : "fffffffffff"))
                      .gggggggggg();
}

I wonder if there is an option to prevent clang-format from breaking the line at the -> operator.

There doesn't seem to be any option only affecting operator-> in the list of clang-format options, but you can always disable clang-format for the offending lines:

int func() {
   // clang-format off
   aaaaaaaaaaa = bbbbbbbb->cccccc(SomeNamespace::Function(dddddddd?"eeeeeeeee":"fffffffffff")).gggggggggg();
   // clang-format on
}

This disables formatting completely, so some manual intervention may be necessary if other formatting rules are desired for the lines in question.
