ERROR 1005 (HY000): Can't create table '.\testDataBase\#sql-ec4_c.frm' (errno: 139)

[Sunil Vishwas]

(I am using mysql-5.0.15-win32)
Why I am getting this error and is there any way I can fix it, or is it
a bug?
Between I don't get this error if I change the field size to 767 or
below:
 
drop table Address;

CREATE TABLE `Address` 
(
 `RecId` CHAR(32) NOT NULL, 
 `WebAddress` VARCHAR(1000), 
 CONSTRAINT PKAddress PRIMARY KEY(RecId)
);
 
CREATE INDEX AddressWebAddressWebAddress ON Address (WebAddress);
