TBaseVirtualTree.PackArray() where it executes assembler on Win32 is the problem
asm
PUSH EBX
PUSH EDI
PUSH ESI
MOV ESI, EDX
MOV EDX, -1
JCXZ @@Finish // Empty list?
INC EDX // init remaining entries counter
MOV EDI, ESI // source and destination point to the list memory
MOV EBX, 1 // use a register instead of immediate operant to check against
@@PreScan:
TEST [ESI], EBX // do the fastest scan possible to find the first entry
// which must be removed
JNZ @@DoMainLoop
INC EDX
ADD ESI, 4

AQTime has problems with this.
The solution is to modify the conditional define and use the Pascal code that would normally be used for the 64bit build.
