So the null in edi comes from edx, which I'd have expected to be set by the function at 5ee8747a if its return value is 64-bit -- but I don't see that function setting edx, so I expect it has a 32-bit return value: 5ee8747a 50 push eax 5ee8747b 64ff3500000000 push dword ptr fs:[0] 5ee87482 8d44240c lea eax,[esp+0Ch] 5ee87486 2b64240c sub esp,dword ptr [esp+0Ch] 5ee8748a 53 push ebx 5ee8748b 56 push esi 5ee8748c 57 push edi 5ee8748d 8928 mov dword ptr [eax],ebp 5ee8748f 8be8 mov ebp,eax 5ee87491 a1304bea5e mov eax,dword ptr [shlxthdl!DllCanUnloadNow+0x3ae20 (5eea4b30)] 5ee87496 33c5 xor eax,ebp 5ee87498 50 push eax 5ee87499 8965f0 mov dword ptr [ebp-10h],esp 5ee8749c ff75fc push dword ptr [ebp-4] 5ee8749f c745fcffffffff mov dword ptr [ebp-4],0FFFFFFFFh 5ee874a6 8d45f4 lea eax,[ebp-0Ch] 5ee874a9 64a300000000 mov dword ptr fs:[00000000h],eax 5ee874af c3 ret Not sure I've analyzed that properly, hope it helps. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Libreoffice-bugs mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs
