            Bug ID: 44432
           Summary: AArch64: assertion fail in alloc_pages_vprot
           Product: Wine
           Version: 3.0
          Hardware: aarch64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: wine-bugs at winehq.org
          Reporter: piotr.caban at gmail.com
      Distribution: ---

Wine sometimes fail to start in qemu_aarch64 + ubuntu16.04 because of assertion
fail in alloc_pages_vprot function.

It looks like it's related to address space limit being set incorrectly in
virtual_init:
#ifdef _WIN64
    address_space_limit = (void *)(((1UL << 47) - 1) & ~page_mask);
After changing it to:
    address_space_limit = (void*)(((1UL << 48) - 1) & ~page_mask);
wine starts successfully. According to arm8 documentation 48-bit virtual memory
addressing is used.
