From the log, it seems it's the upb header missing when building php. @TeBoring would you like to take a look?

i dont know why gdb prompt upd.h is no found.Actually upd.h is included while building php.it is coredump at line 1264 in udp.h(func upb_inttable_lookup32):
UPB_INLINE bool upb_inttable_lookup32(const upb_inttable *t, uint32_t key,
upb_value *v) {
v = upb_value_int32(0); / Silence compiler warnings. */
if (key < t->array_size) { ----------->here, t is point to a upb_inttable struct,but it's value from
dispatch = (upb_inttable *) 0x5f4b0fb800000055(dispatch is a odd address,under the MIPS64 architecture, gdb will throw "BUS Error" and generate a coredump).

In my analysis,
upd.h(Line:1264) upb_inttable_lookup32 t = dispatch;
upd.c(Line:9789) int32_t dispatch upb_inttable dispatch = d->top->dispatch;
upd.c(Line:9908) size_t run_decoder_vm memcpy(&d->top->dispatch, d->pc, sizeof(void));

d->pc is pointed to a static upb_fielddef.maybe a odd address?

Does the error still exist in 3.6.0 release?
