            Bug ID: 59792
           Summary: Sentinel HASP 'hardlock.sys' kernel driver fails to
                    load, because of segfault in IsBadReadPtr.
           Product: Wine
           Version: 11.9
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Looking at bug #59791 I came to bug #50201 and tried if that may already
be fixed. But the installer did not even install the aksfridge driver,
because the hardlock driver failed already before, because below
instruction receives a segfault while storing some context:

1: x/i $pc
=> 0x6fffffa84fbb <__wine_setjmpex+59>: movdqa %xmm6,0x60(%rcx)
(rr) bt
#0 __wine_setjmpex () from dlls/kernel32/x86_64-windows/kernel32.dll
#1 IsBadReadPtr (ptr=0x6ffffe3ff000, size=1) at dlls/kernel32/virtual.c:91
#2 MmIsAddressValid at dlls/ntoskrnl.exe/ntoskrnl.c:2978

(rr) print/x $rcx
$1 = 0x7ffffec2fa68

I wondered if this could be an alignemnt issue, I added following
just to get a even value in $rcx, and it looks like it avoided the segfault.

 __ASM_GLOBAL_FUNC( __wine_setjmpex,
+                   "andq $~15,%rcx\n\t"
                    "movq %rdx,(%rcx)\n\t"          /* jmp_buf->Frame */

But I am not sure how a proper fix should look like,
or if IsBadReadPtr is supposed to work under that condition.
