Another GCC 6 & Rawhide build failure

[Tom Callaway]

First the C++ code:

namespace Amanith {

struct GNamedSVGcolor {
        GChar8 Name[22];
        GVector4 RGBA;
};

static const GNamedSVGcolor SVGColors[147] = {

        { "aliceblue", GVector4(0.941, 0.973, 1.000, 1.000) },
        { "antiquewhite", GVector4(0.980, 0.922, 0.843, 1.000) },
        { "aqua", GVector4(0.000, 1.000, 1.000, 1.000) },
        { "aquamarine", GVector4(0.498, 1.000, 0.831, 1.000) },
        { "azure", GVector4(0.941, 1.000, 1.000, 1.000) },
        { "beige", GVector4(0.961, 0.961, 0.863, 1.000) },
        { "bisque", GVector4(1.000, 0.894, 0.769, 1.000) },
        { "black", GVector4(0.000, 0.000, 0.000, 1.000) },
        { "blanchedalmond", GVector4(1.000, 0.922, 0.804, 1.000) },
...
        { "yellowgreen", GVector4(0.604, 0.804, 0.196, 1.000) }
};

// Yes, it initializes all elements of the SVGColors[147].

}

******

Now, the GCC 6 errors:

../src/rendering/gopenglboard.cpp:280:1: error: C99 designator
'Amanith::GNamedSVGcolor::Name' outside aggregate initializer
 };
 ^
../src/rendering/gopenglboard.cpp:280:1: error: C99 designator
'Amanith::GNamedSVGcolor::Name' outside aggregate initializer
(This repeats 146 more times)

Ideas?

Please tells us which package and which build.  This needs more context

Okay, self-contained test case is:

struct GVector4 {
  GVector4(int);
};
struct GNamedSVGcolor {
  char Name[22];
  GVector4 RGBA;
};

static const GNamedSVGcolor SVGColors[1] = {
  { "aliceblue", GVector4(1) },
};

The RGBA member and the constructor argument appear required to trigger
this.

I agree. Is anything explicitly wrong with that test case? It feels like
a false positive, but I'm not expert enough in C++ to be sure.

Looks like a g++ bug; I opened
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69658
to track it further.

Thanks. Always nice to have someone else agree that it probably isn't my
fault. :D
