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

by "Skybuck Flying" <spam@[EMAIL PROTECTED] > Mar 18, 2008 at 11:51 AM

Index is part of the object/class.

This time it doesn't crash at index := 0; immediatly but later on after a 
number of calls.

I suspect something fishy is going on with esp, since the code does manual

calculations for that...

Still kinda strange that it's working in debug but not in optimizations.

Well I don't have time to investigate now... maybe later I can 
investigate... but I can't do everything myself.

I am hoping somebody will look a little bit at the asm and immediatly spot

the problem.

If it really is a complex problem like byte alignment or even worse a 
compiler problem then I am pretty much screwed.

I also wrote to the mailing list of crypt++ maybe they can help.

Bye,
  Skybuck.

Delphi re-ordering memory as an "optimization" ?

Probably register issue, like esi, edi, whatever. pushad, popad

Still 105 MB/sec not bad :)
