Sorry I didn't think it was so different.
So I search in the mailing list and I don't find something about the gcc 4.x and
problem with the samples. So I try to increase, like you say, the minimun stack
size in this way ;
#define CONFIGURE_EXTRA_TASK_STACKS (100 * RTEMS_MINIMUM_STACK_SIZE)
but it's the same problem, may be I have to set another one costant ?
Thanks in advance
