It seems you're trying to access a field in the L2Cache entry for an
address not present in the cache. That is you have added an
"cacheMemory[address].whatever" (or L2cacheMemory[address].xxx) where
isTagPresent(address) is false. To find the offending line, you can
recompile the tester with "-ggdb", run it with gdb and get the calling
stack using gdb's command "backtrace" when the assertion fails.
