When selecting an image field from a table sybase_query
causes a segmentation fault in apache server.
The error occures when converting datatype image to char in
file php_sybase_db.c function php_sybase_get_column_content.
The problem is that the buffer is to small for the hex-string.
The buffer had to be the double size because a char is translated in 2 bytes.
If you increase the buffersize to 2*res_length its ok.

SQL-Server 2000 submits type SYBIMAGE as datatype.
In file php_sybase_db.c function php_sybase_get_column_content only the types SYBBINARY and SYBVARBINARY are updated with double buffer size, not the SYBIMAGE which is submitted from SQL2000.
