RE: [ECOS] Separate the heap from bss section

[Ho Shui Choy Stanley PS03B NCS <scho at ncs dot com dot sg>]

I have found out that when the heap section is defined in the same memory
region with bss section, then only it will use the specify heap. When the
bss section and the heap is defined in different memory region, the heap
count will be 0. Why is this so? Is it a known bug?

Yes, but changing it by hand won't do the right thing. Try deleting the
heaps.cxx file in the services/memalloc/common/current build directory. The
problem you are seeing may be associated with this FIXME in the CDL:

       # FIXME this should have a dependency on mlt_headers, but CDL
doesn't
        # permit custom build rules depending on phony targets
