           Summary: main.c:286 (endOfInstr): Assertion 'ii->cost_offset ==
                    *cost_offset' failed
           Product: valgrind
           Version: 3.3.1
          Platform: Debian testing
        OS/Version: Linux

When I try to use --simulate-cache=yes with my software on my amd64 Debian
box, I get the following assertion failure:

Note: see also the FAQ.txt in the source distribution.
It contains workarounds to several common problems.

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what Linux distro you are using.  Thanks.
------------------------------------------------------------

Without --simulate-cache=yes, everything works. Manually specifying
cache size does not help, it removes the warnings about cache size but
does not remove the assertion failure.
