Error description
The SQL Server operator incorrectly calculates the size of the bind buffer for a DECIMAL column as 1 byte too short. This causes the conversion from DECIMAL to BCP format (string) to overrun the heap. This subtle heap corruption issue may or may not cause a segmentation violation or the fatal message Unexpected exit status -1,073,740,940.
Local fix
Problem summary
A decimal value must be converted to a string in order to satisfy the BCP Load format. The string length is precision plus 2. Add 1 is for the leading space or plus or minus sign and 1 for the decimal separator. The string value is NOT null-terminated. The 1st 4 bytes in the buffer represent the length of the string. The SQL Server Operator code was modified to provide a buffer of precision+2 instead of precision+1.
Problem conclusion
The heap corruption of BCP Load was solved.
