RTEMS malloc crash.

[Nick Thomas]

Hi,

What would cause a call to malloc to crash in RTEMS?

I presume that I am out of heap memory because my code calls malloc a few
times before it crashes.
The amount of memory it is trying to allocate is not great, about 20 bytes
or so.

I am using PPC405.
The debugger shows that I am down in _Heap_Block_allocate, and the crash is:
Vector: 0x0200 (Machine Check).

Any help appreciated.


Regards

Nick
