dlmalloc-2.6.4.c MALLOC_COPY broken?

Where does dlmalloc come from?

eCos seems to be lacking some upstream bugfixes...



memcpy does not support overlapping memory ranges, which causes problems with
optimized versions of memcpy.

I haven't analyzed it enough to tell whether eCos is bitten by this.
