Sorry forgot to mention, I'm using RTEMS 4.6.6.
Also note that I've tried calloc which gives me the same problem.

Subject: malloc problem


I am working on an application running on 386 with custom built BSP.
 
Calls to malloc in my application keep returning a null value.
malloc_free_space reports a free heap of 3.9M (as I would expect for my
configuration).
I've tried multiple calls to malloc interleaved with a check of the free
heap and it indicates that the free heap goes down correctly in line
with the memory I try to malloc but malloc always returns null.
 
Is that a known bug with malloc? Or am I missing something somewhere?
 
Thanks for your helps
 
Sam
