--- Comment #4 from Martin Liška ---
Maybe a bit different backtrace:
$ cat trigger.i
typedef struct {

_Bool trig_update_after_row;
_Bool trig_update_instead_row;
_Bool trig_update_before_statement;
_Bool trig_update_after_statement;
_Bool trig_delete_before_row;
_Bool trig_delete_after_row;
_Bool trig_delete_instead_row;
_Bool trig_delete_before_statement;
_Bool trig_delete_after_statement;
_Bool trig_truncate_before_statement;
} TriggerDesc;
void SetTriggerFlags();
void

int i;
for (; i; i++)
SetTriggerFlags();
}
void
SetTriggerFlags(TriggerDesc *trigdesc) {
short tgtype;
trigdesc->trig_insert_before_row |= trigdesc->trig_insert_after_row |=
