Looks like clang has found a real issue here:
/usr/src/sys/x86/x86/local_apic.c:311:2: warning: array index of '-16' indexes
before the beginning of the array [-Warray-bounds]
lapics[apic_id].la_ioint_irqs[IDT_DTRACE_RET - APIC_IO_INTS] =
IRQ_DTRACE_RET;
IDT_DTRACE_RET (0x20) indeed seems to be less than APIC_IO_INTS.
