--- Comment #5 from Martin Sebor <msebor at gcc dot gnu.org> ---
Stack trace is below. Bisecting a test case with the initializer changed to
the equivalent '{ }' points to r198746 as the first revision when GCC failed
with an ICE. Prior to that, GCC rejected the code with:
pr93730.C: error: variable-sized object ‘DefaultGammaTable’ may not be
initialized
int DefaultGammaTable[3][Seed] = {{0,},};
^
pr93730.C:4:15: warning: unused variable ‘DefaultGammaTable’
[-Wunused-variable]
4 | unsigned int DefaultGammaTable[3][Seed] = {{0,},};
| ^~~~~~~~~~~~~~~~~

pr93730.C:4:15: internal compiler error: in make_decl_rtl, at varasm.c:1346
