Hi, I tried to use gem5 to run SPEC2006 in x86 O3 mode. When I ran bzip2, it failed with: fatal: Over max stack size for one thread My command line is: build/X86/gem5.fast configs/example/se.py --cpu-type=detailed --caches -c bzip2 -o "input.program 5" The version of my gem5 is 8981. Bzip2 can run correctly in atomic mode. I binary searched where the problem happened first, and found version 8842. I noticed this patch is about branch prediction, and I don't understand why this can affect the correctness of an application. Before 8842, Bzip2 can run correctly in both mode, but the outputed numbers of "info: Increasing stack size by one page." are not equal. Because of email size limitation, I can't attached the file I used.
