Thanks a lot, I will try this but
I take a look in the libc_start_hook() function and
I have the reent structure allocated with calloc, so
it should be in heap, no ?
In fact, I have just look at the CVS, this feature is
true since rtems-4.6.0-pre5 and rtems-4.6.0-branch but
I use the rtems-4.6.0-pre4 so, reent struct still
allocate
in my heap.
Any idea ?
