Do you have backtrace available?

There is a bug report with a similar error diagnostic here: #54423

Sure, the reproducer still works as of ae86239e86e9e289167fad2d7465d254852ecb82:

[Endilll]

I compiled Clang at the specified commit, and was able to reproduce.
Appears to be a post-17 regression that is currently fixed: https://godbolt.org/z/zrhG9hq64
I think it was fixed by #76348. @bwendling might be interested in additional test case.
Reduced by me and C-Reduce:

typedef struct irq_data {
  struct irq_domain *domain;
};

struct irq_domain {
  const char name;
  unsigned int revmap_size;
  struct irq_data *revmap[]
      __attribute__((__counted_by__(revmap_size)));
};

struct irq_data irq_domain_fix_revmap_d;
unsigned long irq_domain_fix_revmap_d_0;
static void irq_domain_fix_revmap() {
  *&irq_domain_fix_revmap_d.domain->revmap[irq_domain_fix_revmap_d_0] = 0;
}
void irq_domain_push_irq() { irq_domain_fix_revmap; }

Post-17 trunk crash:
