BUG #: 356323 (SHILOH_BUGS)
In SQL Server 2000 Service Pack 2 (SP2), when you run a SQL Profiler trace that includes RPC events (RPC:Starting or RPC:Completed), a statement that includes a bit parameter that has a value that is greater than 9 causes an access violation in CNetInputBuffer::Init.
In SQL Server 2000 Service Pack 1 (SP1), the trace is truncated, and you receive an error message in SQL Profiler, but no access violation occurs in SQL Server. The data type of the table column is irrelevant; only the data type of the parameter is relevant to this problem.
NOTE: The table column may be another type other than bit.
SQL Server 2000 SP2 (8.00.534) generates the following stack dump:

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.
To reproduce the access violation, run a SQL Profiler trace that includes at least one of the RPC events (RPC:Starting or RPC:Completed), and then run the following C code:
This access violation occurs when the server is running SQL Server 2000 SP2; the SQL Profiler tool version does not affect this problem.
