[ICE] no stopping condition for aggregate_initializer

[jyn514]

Code

struct D { struct D segs[]; }bar (struct D *svp)
{
svp->segs[asi];
}

thread 'main' has overflowed its stack
fatal runtime error: stack overflow
Aborted (core dumped)

Expected behavior

<stdin>:1:25: error: array has incomplete element type 'struct D'
struct D { struct D segs[]; }bar (struct D *svp)
                        ^
<stdin>:1:8: note: definition of 'struct D' is not complete until the closing '}'
struct D { struct D segs[]; }bar (struct D *svp)
       ^

cc @hdamron17 , this is the same issue with not recognizing incomplete types.
