My project causes OllyDbg to crash

[Shooter]

I'm not sure if it's allowed to post my problem on this forum, so if it is, please let me know.

I've compiled an executable that does mostly what I want it to do, except I'm trying to move some code into it's own proc (ChangeTextColor). I've enabled the /debug feature during compiling and now when I try to step through it, Olly crashes, and I don't know why.

First of all, I'd like to know if anyone else can duplicate the crash.

Secondly, can anyone help, both with the crash and what I'm attempting to do? (There seems to have been an issue with passing a handle to the proc. That's where I was stuck at prior to the crashing.)

Thanks,

sometimes it helps to delete the corresponding *.udd-file from Olly's directory.

Thanks. When I performed a Google search for a forum, I got quite a number of websites, and some didn't look legitimate.

Yeah, Oleh should really update his website, he moved to woodmann years ago but still has the link to Hiro's board.

When I did this (delete udd), mine is 8,735 in size versus your 39,048.  I single steped through the program and it functioned in OLLY without a hitch.  Should I be catching it in one of your procedures?

I noticed it appears to crash in the ChgTxtClr proc. It also crashed when I attempted to set a watch for ss:[ebp+10], a breakpoint at that location (push dword ptr ss:[ebp+10], and running until that breakpoint.

Attached a Masm-compliant version, with proper paths (not everybody has E:\...).
It does not crash on my PC with Win XP SP2.

By the way, ChgTxtClr seems not to have any effect, but it should work without crashing...

Congrats that you got the debug build to work :U

I concur with JJ and my system is;

XP Pro SP 3
     ml  6.15.8803
link Ms 5.12.8078
      Rc 5.00.1823.1 - Build 1823
    Olly  1.10

I did notice your executable was a little different than mine as in a jump table @ 401000, which I've only come across using VC 6.0.  Maybe somewhere in this will like to clue.
