Re: Crypt++ 5.5.2 Tiger::Transform converted to DCPCrypt2.Compress, AV: Compiler Optimization Bug with SSE2 ? Or just programming bug ? HELP NEEDED :) ?!

I compiled with free pascal too.

Sample problem there:

Works with optimizations off, crashes with optimizations on ?!?

I also inspected the asm for some sections and it seems the same (Delphi:)

Good:

DCPtiger_optimized_version_201.pas.84: begin
0041044C 55               push ebp
0041044D 8BEC             mov ebp,esp
0041044F 83C4F4           add esp,-$0c
00410452 894DF8           mov [ebp-$08],ecx
00410455 8955FC           mov [ebp-$04],edx
00410458 8945F4           mov [ebp-$0c],eax
DCPtiger_optimized_version_201.pas.90: lea edx, [TigerTable]
0041045B 8D15683A4100     lea edx,[$00413a68]

....

DCPtiger_optimized_version_201.pas.514: Index:= 0;
00410ABE 8B45F4           mov eax,[ebp-$0c]
00410AC1 33D2             xor edx,edx
00410AC3 895010           mov [eax+$10],edx
DCPtiger_optimized_version_201.pas.515: 
FillChar(HashBuffer,Sizeof(HashBuffer),0);
00410AC6 8B45F4           mov eax,[ebp-$0c]
00410AC9 83C030           add eax,$30
00410ACC 33C9             xor ecx,ecx
00410ACE BA40000000       mov edx,$00000040
00410AD3 E8D029FFFF       call @[EMAIL PROTECTED]
 end;
00410AD8 8BE5             mov esp,ebp
00410ADA 5D               pop ebp
00410ADB C3               ret

SAME ?

Bad:
