test case 1

This seems to be related to straight nested braces. I have two test cases:

case 1:

LZ4F_preferences_t prefs = { {
    LZ4F_default,
    LZ4F_blockLinked,
    LZ4F_contentChecksumEnabled,
    LZ4F_frame,
    cbSource,
    0,
    LZ4F_blockChecksumEnabled,
} };

trunk gives

LZ4F_preferences_t prefs = {
    {
     LZ4F_default, LZ4F_blockLinked,
     LZ4F_contentChecksumEnabled, LZ4F_frame,
     cbSource, 0,
     LZ4F_blockChecksumEnabled, }
};

13.0.0 crashes.

case 2:

class Derived : Base
{
    void foo()
    {
#ifndef _MSC_VER
        const Object object = { {SOME_MACRO, { opt, someMember }} };
#else
#endif
    }
};

trunk & 13.0.0 give

class Derived : Base
{
    void foo()
    {
#ifndef _MSC_VER
        const Object object = {
            {SOME_MACRO,
             { opt,
             someMember }}
        };
#else
#endif
    }
};</pre>
        </div>
      </p>
