I've got serious problems using dev-c++ 4.9.8.9 under
Win NT with activated Class Browsing (only project
header files will be parsed) and deactivated
autocompletion:

The following error occured in version 4.9.8.9:
A call to an OS function failed (at address 0x0040F11A)

Please include a description of what you were doing
before the error occured (please give as much precisions

Same thing with me. I am using 4.9.8.9 on Windows XP home.
Whenever I use the class browser, I get an error message for
an access violation. Most of the time I can continue working
after the bug, but every once and a while this freezes up my
computer.

Same here. I am using XP pro. I submitted bug report, but I
have the feeling that it never got through....

Looks like a code tooltip problem, peter can you please look
into your code ?

Hi,

unfortunalety I cannot reproduce the error at all :(
I'm using WinXP Pro (english) with SP1.

I did follow the bug description above and turned off
autocompletion and activated classbrowsing, but still no error.

Here is the codesnipple to what the exceptionlogger points to:

// clear the backbuffer with FBmp.Canvas do begin Brush.Color := Self.Color; FillRect(ClientRect); // this is line 768 end;

Any idea what could be wrong with that FillRect call?

Colin, can you reproduce the error?

the "send bug report" button doesn't work either, and having
autocomplete crash each time it is used makes it useless.
it was autocompleting a variable of type SYSTIME struct
(declared in windows.h i think) when it reliably ;-) crashes
