Error "1 (Error INF)" in InfoView when using ; as separator of value

Question

Can anyone explain me this change of Behaviour before I log a bug ?
Here is the workflow :
1. Create a new WebI report using EMP from Oracle
2. Use Empno, Ename, Job and Mgr objects
3. Put a query filter on Mgr object In list and then prompt
4. Run the query and then select few values
5. save the report
6. Open the report in Interactive mode
7.In the left pane 'User Prompt Input' overwrite the existing value by manually inserting new ones separated by ;
8. Select advanced button
-> report is running fine
Do the same workflow as above in BOXIR2 sp4
-> error 1(Error INF) is coming up
modify the separator by a , and then no error is coming up prompt is then showing
Why is that ? Has there been some changes done between the 2 versions ?

Dear Mat,
While more details are desirable to give precise answer I guess that I know the origins of the problem. VML functions are thread-safe. VML engineers use Mircosoft TLS mechanism to maintain thread safety of VML global variables. The TLS use is different for static and dynamic case. This implies that it is impossible to use MKL static library which contains TLS stuff to build dynamic library. Indeed, your DllMain function must have VML TLS initialization/processing/finalization stuff (for details see http://msdn2.microsoft.com/en-us/library/ms686997.​aspx). In case VML TLS stuff is absent in your DllMain routine you will see Access Violation on any attempt to access VML global variables.
VML engeneers are seeking for possible solutions/workarounds. Thus far they don't see any elegant way of solving this with existing technologies. Specifically, _mkl_vml_core_w7_vml_GetMode routine does access one of VML global variables.
There is a possibility to build custom VML DLL from static MKL library using MKL Builder Tool. The limitation is that the built DLL cannot contain non-MKL stuff (recalling DllMain issue, MKL Builder Tool cannot put into DllMain routine user's stuff).
Feel free to go to Intel MKL web forum or contact Intel Tech Support in case you have additional questions.
I will keep you informed.
