Crash deep in heap allocation for rtems_region_get_segment() call

[Matthew J Fletcher]

Hi

So the current block is 0x70b0bef8 with a size_and_flag of 257, block->next
is 0x70b0c9f8 with a size_and_flag of 3444481, block->prev is 0x701615b8
with a size_and_flag of 0.

I note that the 'prev' and the 'free_list_anchor' are the same, as is the
'heap' pointer, not sure if thats normal ?


I would normally presume this is a BSP / my_platform issue, but my linker
script has the following, which looks fine.

 "SDRAM      : ORIGIN = 0x70000000, LENGTH = 0x01000000"
 "RTEMS_AREA : ORIGIN = ORIGIN (SDRAM), LENGTH = 9216k"  // APP_BSS and
APP_HEAP are after this, so 9216k is somewhat arbitrary.
