CCS: opt6x.exe experienced a segmentation fault ?

Dear all,

by adding some neglectible if's to a c-file i get a strange error from Code 
Composer Studio's compiler:

----------------------------------------------------------------------------------------------------------------------------
...
INTERNAL ERROR: C:\CCS31\C6000 Code Generation Tools 5.1.6\bin\opt6x.exe 
experienced a segmentation fault while
                processing function _newhandling file 
C:\DOKUME~1\X9FA3~1.GRE\LOKALE~1\Temp\TI7242

This is a serious problem.  Please contact Customer
Support with this message and a copy of the input file
and help us to continue to make the tools more robust.

>> Compilation failure

[Linking...] "C:\CCS31\C6000 Code Generation Tools 
5.1.6\bin\cl6x" -@"Debug.lkf"
<Linking>

Build Complete,
  0 Errors, 5 Warnings, 0 Remarks.
----------------------------------------------------------------------------------------------------------------------------

Anyway he's linking the Project but i do not feel good with it.
(5 warnings are neglectible other things)

Has anybody seen this before ?
Does someone know what a segmentation fault could be ?

                    Any suggestions welcome,
                                                Greg.

A segmentation fault indicates a memory access that the program isn't
supposed to be able to do:

http://en.wikipedia.org/wiki/Segmentation_fault

This is a very common type of programming error. As the error message
indicates, you're probably best off referring this to TI's technical
support.

Thanks Jason for your help.
At least it can't be a simple segmentation fault as it occured first by
adding a simple if (the variables were used before also).
Also it vanishes if i change the compiler options (optimize / debug etc.).
By searching on TI's resources there is no indication of a segmentation 
fault
problem in opt6x.

            Thanks for the wiki-link. Didn't thought I could find that topic 
there.

                            Regards, Greg.

The segmentation violation does not occur in your code, but in the
program opt6x.exe supplied by TI. Therefore you should contact TI.
