Hello everyone, I am trying to run different SPECCPU 2006 benchmarks on gem5 is SE mode but for some of the benchmarks, the simulation prints the following line: "info: Increasing stack size by one page." a bunch of times and then aborts prematurely citing the reason: "gem5 has encountered a segmentation fault!" I have two questions: 1. What does the line "info: Increasing stack size by one page." exactly mean? 2. How to fix segmentation fault issue? I've tried increasing memory size in se.py (--mem-size) but of no use. Is there any place where I can increase the stack size to try to fix this problem? Any help would be greatly appreciated :) Thanks Sam

The message about increasing the stack size is normal. In SE mode the stack grows on demand, and that's just letting you know it added a new page.
