On SQL2005 i ran a DB Update script. Among a lot of other things it does (re)create a lot of indexes. On a few indexes we get the following error:

ERROR : A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a QFE from Technical Support.

Now i tried DBCC with all different options, but it did not find any corruption.

In an effort to resolve this issue i also applied the latest hotfix, SQLServer2005-KB953752-x86-ENU.exe. This did not fix the problem.

Is this a bug, will we need to have Microsoft have a look at it?

Me too.
Getting this error running an INSERT statement with (TABLOCK). Resulting in a Stack dump. The table is NOT compressed/replicated, CHECKDB does not reveal any errors. Using SQL Server 2008 R2 build 10.50.1600.1 (no Service Packs).

Error log excerpts :

A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a QFE from Technical Support.

SQL Server Assertion: File: <pageref.cpp>, line=922 Failed Assertion = 'IS_OFF (BUF_MINLOGGED, m_buf->bstat) || pageModifyType != PageModifyType_Contents || GetPagePtr ()->IsTextPage ()'. This error may be timing-related. If the error persists after rerunning the statement, use DBCC CHECKDB to check the database for structural integrity, or restart the server to ensure in-memory data structures are not corrupted.
