The actual overrun here is not the one the backtrace describes. The
first "writel 0x8000f00 0x5affaf" writes a value to GICD_SGIR which
overruns the sgi_pending array in the GICState structure. In particular,
it overwrites the s->num_irq field, which is what is guarding the array
access to gic_irq_state[] that the "write 0x8000eff 0x1 0x0" exercises.
With the first overrun fixed, the check for "if (irq >= s->num_irq)"
functions correctly.
