i have problems with some code of mine and i'm wondering if it's my fault

. i get strange errors when using combinations of EnableDebugger/DisableDebugger.
for example i have "DisableDebugger" in the beginning of the code, and later on..

Code: Select all

IncludeFile ...
EnableDebugger
IncludeFile "units_process.pbi"
DisableDebugger
IncludeFile ...

in the included file i get an "array index out of bounds"

Code: Select all

            Debug u
            Debug ArraySize(unit())
            Debug unit(u)\go_i
            Debug unit(u)\go_k
            Debug ArraySize(mp(),1)
            Debug ArraySize(mp(),2)
            Debug ArraySize(mp(),3)
            mp(unit(u)\go_i, unit(u)\go_k, 2) = #farm01 ;          <--------- error here

where the debug output is the following

Code: Select all

so actually that error should not occur.
additionally, the error does not occur if i comment out the "DisableDebugger" in the line next to the include statement or if i don't use En/DisableDebugger at all. also the programm is running fine when compiled without debugger.

at another time i had the error "InitKeyboard() must be called before.." at ExamineKeyboard(), though InitKeyboard was called successfully. this also disappeared when changing the debugger statements.
i'm using no threads, but a little memory stuff and pokes here and there (

).
tested with pb 430,431 and 440b3, all the same.
unfortunately i can't reproduce this in smaller snippets, so i have to upload the necessary files (482kb zip / >10.000 lines of code).

[link removed]

i merged the includefiles to one file, so that now the lines with Enable/DisableDebugger are:
6
7830
7403
and the error occurs at line 7535
if the program has started and you can see the screen, press F3 to load a saved state. within some second the error schould occur.

onestly, i don't expect somebody can help me with this, since i cannot assure it isn't simply a bug i produced by corrupting memory of pb-internals. on the other hand there's a chance that it's a pb bug, but i understand if fred/freak doesn't want to spend time on this eventuality.

any idea is appreciated.

It seems like the debugger doesn't pick up the allocation of multidimensional arrays after DisableDebugger, so it thinks the bounds is -1 for all dimensions.

Code: Select all

DisableDebugger
Global Dim Funkstyle(10, 10, 10)
Global Dim Chopin(1923)
EnableDebugger
CallDebugger
; Look in the variable viewer

In my opinion it's a bug, since single dimension arrays works.

thank you very much for having a look at it. that helps me a lot so i can continue with this program without having to use the debugger throughout all the code.

there is another little thing:
on 'CallDebugger' the IDE highlights and jumps to the last 'DisableDebugger' if there is such, instead of showing the actual position:

Code: Select all

DisableDebugger

CallDebugger

to find the 'CallDebugger' in big sources with many includes becomes difficult, because the error log neither says where the call was.

another example

Code: Select all

DisableDebugger
InitKeyboard()
EnableDebugger
ExamineKeyboard() ; error

i'm suprised this is how a debugger should work. anyway it probably won't change in the future and it's ok once you know what's going on (but can be weird if you don't).
