Hi!
The problem is that if try to write to a file without 'fields
terminated by', then MySQL assumes you want to write with fixed record
length. There was a bug where MySQL, in this case, filled an internal
buffer with 2^24 space.
The following fix changes the behaveour of MySQL so that if you use a
blob, mediumblob or longblob, then it will never assume fixed file
format.
