--- Comment #5 from Martin Sebor <msebor at gcc dot gnu.org> ---
The trigger seems to be __PRETTY_FUNCTION__.  Below is a smaller test case:
constexpr int ce (int r)
{
   const char *s = __PRETTY_FUNCTION__;
   return r;
}

constexpr int i = ce (3);

v.c: In function ‘constexpr int ce(int)’:
v.c:3:16: warning: unused variable ‘s’ [-Wunused-variable]
    const char *s = __PRETTY_FUNCTION__;
                ^
v.c: At global scope:
v.c:7:22:   in constexpr expansion of ‘ce(3)’
v.c:7:24: internal compiler error: Segmentation fault
 constexpr int i = ce (3);
                        ^
