I get wrong indentation behavior for C++ mode.
The following snippet produces this behavior:
----------------------------------------------------
This happens:
SomeBase::SomeDerived::SomeFunction(const std::vector< int >& in_somevector,
                                    const std::vector< int >& in_someothervector,
                                    const glm::vec3 in_aglmvector,
                                    const glm::vec3 in_someotherglmvector,
                                    const int in_someint,
                                    const int in_someotherint,
                                    const float in_somefloat,
                                    std::vector< int >& in_someints)
: somevector(in_somevector)
                                                         , someint(in_someint) {
}
----------------------------------------------------
This is expected:
SomeBase::SomeDerived::SomeFunction(const std::vector< int >& in_somevector,
                                    const std::vector< int >& in_someothervector,
                                    const glm::vec3 in_aglmvector,
                                    const glm::vec3 in_someotherglmvector,
                                    const int in_someint,
                                    const int in_someotherint,
                                    const float in_somefloat,
                                    std::vector< int >& in_someints)
  : somevector(in_somevector)
  , someint(in_someint) {
}
----------------------------------------------------
The failed indentation seems to be related to the length of the
function header, though I did not do extensive testing.
The bug could be reproduced on at least 1 other machine.
I know this probably has low priority, but it's driving me insane, hope
it can be fixed easily :)

Thanks for a great piece of software!
