Hello,
This is the tiger transform routine/procedure/method converted from the
Crypt++ 5.5.2 C/C++/Asm code to DCPCrypt2 Delphi/Pascal/Basm code.
It works with optimizations turned off.
As soon as optimizations are turned on, it crashes with an access violation
as soon as Index := 0; is executed.
I am not sure what the problem is because:
1. I didn't write the asm code.
2. I am not an asm expert.
I did my best converting it.
I think some possible causes might be:
1. Mis-aligned of byte boundaries ? (Maybe the C/C++/Asm had to do special
memory alignment ?)
2. Stack issue's ? (Not enough pushes or pops ?) (Framing issue?)
3. Compiler optimization bug ?
Who can tell for sure ?
Problem is in the Compress method.

* This routine calculates how much time the calling process
* has used. At startup time, startup calls __inittime which stores
* the initial time. The clock routine calculates the difference
* between the current time and the initial time.
*
* Clock must reference _cinitime so that _cinitim.asm gets linked in.
* That routine, in turn, puts __inittime in the startup initialization
* routine table.
*
*Entry:
* No parameters.
* itime is a static structure of type timeb.
*
*Exit:
* If successful, clock returns the number of CLK_TCKs (milliseconds)
* that have elapsed. If unsuccessful, clock returns -1.
*
*Exceptions:
* None.
