Hi,Alex When running Squid4.8 on the arm using SMP. And setting 4 or 7,9 worker ,the same error occurred in the log. >> Received Bus Error...dying, Debugging the core file with gdb found that the address was not aligned. Does it consider the case where only address-aligned access is supported on arm The question is, why is the type of Item in the PageStack class using uint32_t, can it be replaced with uint64_t or size_t? When I change to uint64_t, the problem disappears. I tried another way to ensure that the theCapacity parameter passed in to an even number also solves this problem.
