Re: [Xenomai] xenomai 3.0rc4 rt_heap_alloc replies with timeout

["Stéphane ANCELOT" <sancelot@free.fr>]

Hi,
unfortunately, There is something wrong for unknown reason using these 
functions.

I made a simple regression program that only create heaps and allocates 
area.

At line 190 of the file, depending on the size value of the heap, the 
program works or not.
This looks like corrupted memory problem...

enclose is the c file, I hope you will be able reproduce it.
Regards,
Steph
