I'm trying this again with freshly compiled nightly snapshot of FreeTDS and still getting errors:
> src/apps/freebcp foo.dbo.blobs out /tmp/blobs.bcp -c -S MSSQL0 -U *** -P ***
Starting copy...
*** glibc detected *** /tmp/freetds-dev.0.92.377/src/apps/.libs/lt-freebcp: double free or corruption (!prev): 0x000000000196a5c0 ***
Segmentation fault
Am I doing something wrong?

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.bcp1 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?
Constantin
Fixed in both 0.91 and master.
