Problem with eCos stack and data corruption

I've looked at the mallocs, and the test only calls malloc one time. The program counts the times malloc fails, and I have added a check in order to see if malloc returns null.

The result is that my check doesn't appars (it seems that all mallocs succeed), and the tracing of the test is:

So it seems that there's still 0x000b9c34 memory free, so ... I am working on trying the test on the Evaluation board with all the modules, included the SDRAM...
