            Bug ID: 109431
           Summary: internal compiler error: in
                    output_constructor_regular_field (varasm.c:5207)
           Product: gcc
           Version: 9.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gh0s-t at yandex dot ru
  Target Milestone: ---

Created attachment 54815
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54815&action=edit
preprocessed file for short source example

Problem occurs from 9.1 to newer gcc versions. But code compiles on older
convenient gcc versions. godbolt.org used.


As I can see, the problem is in function body static and constexpr keywords
mixing at array aggregate initialization with empty initializer-list (at line
#111 in preprocessed file).


Using built-in specs.

Reduced:
```
struct RangeLimits
{
    int low = 0;
    int high = 1;
    constexpr RangeLimits() { }
};

template <int>
int parameterLimits(void)
{
    static RangeLimits constexpr param_limits[ 2 ] = {};
    auto const &limits = param_limits[ 1 ];
    return 0;
}

auto s = parameterLimits<1>();
```
