I know it will be a tough sell to my bosses. I guess the question is, have I discovered a compiler bug?

    for S&G, try all the normal clean out procedures....

    Grab all the source files from their folders, place them into a new
    folder set. Note, do not grab anything that is not your source... (i.e.
    only take the bare minimum necessary files, VBP, FRM/X, CLS, BAS, CTL/X
    ...)

    Make sure every module (all src files) have Option Explicit.
    Fix everything it complains about

    The next steps get messier as I go along

    Pull everything out of a form that needs to get stuffed into an FRX
    (same for Controls - CTX) This consists of everything that you
    might have set in the properties window for images, pictures, etc.

    Start adding conditional compilation constants/checks into the code to
    hide large portions of your code from the compiler. If you get a clean
    native code compile after any part, you have a good place to start
    narrowing down the spot thats causing the problem.

    I've seen a line of code (that was narrowed down to be the root of the
    problem) get cut and pasted back in and the problem goes away!

    Goog luck...

    heres a few thougts from some OP's post

    The Symptoms:
    - VB crashes whilst writing EXE (toward end of process)
    - Also: VB sometimes crashes when merely viewing the
    Project Properties\Make tab !?!?!
    - NO messages or events whatsoever!
    - Object files (.OBJ) are left in the compilation folder
    - Error occures under Windows 2000 only (same project!)
    - Same project code compiles to EXE without error under
    Windows NT4 (in my case)!!!
    - The exact error also appeared with VERSION 5 (as well as
    VB6)!!!
    - Uninstalling, rebooting and re-insalling does NOT help.
    - I can compile an nearly new project OK (not fully tested
    though)

    Following my search for help today... things I am going to
    try:
    - Disabling Options\Environment\Prompt to Save Changes
    (see Q214427)
    - Disabling Options\General\Background Compiling
    - compiling without Optimisations
    - compiling with P-code option enabled
    - Try setting Project Name to something WITHOUT dots
    (i.e. "MyProgName" rather then "My.Prog.Name")
    - Reducing length of Comments property
    - Make sure I have OCX files registered correctly
    - Uninstall VB6 and VB5m reboot, reinstall VB6 only
    - Disable Addins...
    ===============================
       To prevent add-ins from being loaded when Visual Basic
    starts:
       Start Notepad.exe.
       Edit the VBAddin.INI file in your Windows directory and
    set all of the entries to zero (0). For example:
       Original: AppWizard.Wizard=1
       Modified: AppWizard.Wizard=0
       Save VBAddin.INI.
       Restart Visual Basic.
    ================================
    - Rebuild project by adding forms and modules to a NEW
    project
    - Pull my hair out and jump out of a window !!! (joke) :)

    What I am doing:
    - Compiles OK under Windows NT4 (never has been a problem)
    - Using Windows 2000 (SP2)
    - Using VB5 and VB6 (currently together)

    Conclusions / thoughts:
    - Error occurs in VB5 and VB6 under NT4 and 2000 (so does
    not seem version related?)
    - Thus, the problem could be PROJECT related (perhaps
    corrupt files?)

    VB Project Info:
    - Project is 10,000 lines or so (including comments) !!!!!
    - Contains version 5 common controls (tried 6, same error)
    - [too tired and fed up to list anymore, boo hoo] :(
