Hi,
I have a problem that has appeared with the changeset 9084:ace8383f2b7e.
gem5.fast segfaults and with gem5.debug, an assert statement breaks.
I have tested with the 9083 version and I haven't the problem.
Here is the call stack:
gem5.debug: build/ARM/mem/cache/tags/cacheset.cc:84: void
CacheSet::moveToTail(CacheBlk*): Assertion `i >= 0' failed.
Program received signal SIGABRT, Aborted.
