[freetds] freebcp - problems with blobs >8K

Hi FreeTDS team,

I ran into a problem trying to freebcp some larger blobs in and out of MS SQL 2008 server.
The host table may look like:

create table blobs (id int not null, data image)

Smaller blobs load in and out just fine:

> cat /tmp/blobs.bcp 
1       0123456780
> freebcp foo.dbo.blobs in /tmp/blobs.bcp -S MSSQL0 -c -U **** -P ****

Starting copy...
1 rows copied.

but once the blob gets larger than 8K the command fails with errors like:

Starting copy...
*** glibc detected *** freebcp: free(): corrupted unsorted chunks: 0x0000000002241a90 ***
*** glibc detected *** freebcp: malloc(): memory corruption: 0x0000000002243d10 ***

I tried 0.91 stable and 0.92.377 with the same result.

Any clue?
