The following C code causes a segfault in DMD:

typedef enum
{
        SQL_IS_YEAR                             = 1,
        SQL_IS_MONTH                            = 2,
        SQL_IS_DAY                              = 3,
        SQL_IS_HOUR                             = 4,
        SQL_IS_MINUTE                           = 5,
        SQL_IS_SECOND                           = 6,
        SQL_IS_YEAR_TO_MONTH                    = 7,
        SQL_IS_DAY_TO_HOUR                      = 8,
        SQL_IS_DAY_TO_MINUTE                    = 9,
        SQL_IS_DAY_TO_SECOND                    = 10,
        SQL_IS_HOUR_TO_MINUTE                   = 11,
        SQL_IS_HOUR_TO_SECOND                   = 12,
        SQL_IS_MINUTE_TO_SECOND                 = 13
} SQLINTERVAL;
