I used ObjCond and I got these warnings :
lstrlen LABEL NEAR
; Note: Memory operand is misaligned. Performance penalty
jmp qword ptr [imp_lstrlen] ; 400089CF _ FF. 25, 00005847(rel)
VirtualAlloc:
; Note: Memory operand is misaligned. Performance penalty
jmp qword ptr [imp_VirtualAlloc] ; 400089D5 _ FF. 25, 00005849(rel)
VirtualFree:
; Note: Memory operand is misaligned. Performance penalty
jmp qword ptr [imp_VirtualFree] ; 400089DB _ FF. 25, 0000584B(rel)
lstrcmp LABEL NEAR
; Note: Memory operand is misaligned. Performance penalty
jmp qword ptr [imp_lstrcmp] ; 400089E1 _ FF. 25, 0000584D(rel)
How to avoid them?
