This patch fixes a small mistake in MCDataAtom::addData() where it doesn't ever
call remap():
- if (Data.size() > Begin - End - 1)
+ if (Data.size() > End + 1 - Begin)
remap(Begin, End + 1);
This is currently not visible because of another bug is the disassembler, so
the patch includes a unit test.
Patch by Stephen Checkoway.
