GCC would ICE if the referenced DIE wasn't being output on:
gcc_assert (AT_ref (a)-die_offset);
in output_die.

It's possible that the message from dsymutil is misleading:
Is this correct ?
I'm very new to dwarf - but it looks like the DW_AT_upper_bound is missing a

this causes the message at any optimization 0.
which kinda points to variable length arrays as the issue (wherever that issue
is).
extern long random(void);
int main(int ac,char *av[])
{
int n = random();

The warning was cause for alarm, and the root cause has been fixed (checked
