Bug 190593

Edit 1:
Had also loaded Nvidia restricted drivers so I tried disabling. Same result as before.

Loaded debugging symbols with package manager. Here is the result

The crash appear in new c++ operator to allocate memory when image is loaded...

There is no reason for that. Sound like something is broken in your system...

Andy, Marcel, do you see another stuff ?

Gilles

Something is happening in qimgloader.cpp:99.
We had a similar problem before, at the same line, I think it was while loading a TIF file. This is a simple uchar mem alloc, so I really don't know what could be wrong here. I've never seen new() just crash, this can only happen when no memory is available at all, right?
So this would mean the users memory was completely filled AND the swap is also completely used. And even then new() would work I guess, I wrote some app at university to crash a computer in seconds. It allocated 1GB of RAM per second (also with new()), but it never crashed. The only thing you had to do was plug off the power cable because even keystrokes where not handled anymore :-)

If memory outrun is not the problem, what else can crash new()?

Andi

Here is some "interesting" link (yeah I now, MS sucks ;-)):
http://msdn.microsoft.com/en-us/magazine/cc164087.aspx

This would mean we need to check the return of new every time? But to me it looks like new crashes before it even returns something (note it is happening in line 99, so crash is when actually allocating the mem, not using it somewhere else).

Andi,

Yes. To be sure new must return a valid pointer if allocation is fine. Else, new return 0. So this code can be used :

uchar* myData = new uchar[mySize];
if (!myData) return false;

// myData can be used here.

return true;

But yes, as trace said, crash appear in new operator...

Sure, but I guess we could not just check for the return because it crashes before (like you just said).
Hmm how to debug something like that?

System does seem buggy like it is out of memory while splash screen is visible. slow to respond to mouse movements and clicks. click and application and it take several seconds to respond or doesn't respond until splash screen is gone.

See

http://www.parashift.com/c++-faq-lite/freestore-mgmt.html#faq-16.6

for what the standard says (and what MS is doing...)

David, please enable debug code 50003 with the kdebugdialog tool. I hope that you then get debug messages on the console. I would like to identify the picture that causes this, and it will be the last one printed on the console.

Last line printed:

digikam(8647)/digikam (core) Digikam::DImg::load: "/home/david/Pictures/Microsoft Clip Organizer/6A38B379.bmp"  : QIMAGE file identified

Deleted this image file and digikam starts. Quick check, connect to camera and down load images: ok, can see all images: ok, able to edit image: ok. Seems to be working.

FYI Image is a 440 Mib scan of an old photograph. Thanks for the help!!!

(This is my first bug report, should I mark as resolved or does someone else do that?)

This requires a fix, although it now works for you - we do not need to load the full image at startup. It seems that loading this huge image really is too much for your memory, so it's ok that operator new fails here (We load it as QImage, with the data in the QImage once, then copy it to an internal buffer, so it's at least twice the memory. And raw memory will be more than file size)

Marcel, 

Following your comment #11, do you plan a fix for this entry ?

Gilles Caulier

Yes. Probably, catch the bad_alloc exception in some well selected locations like this one here.

John,

Crash appear in xine phonon plugin. Check libxine package...

Gilles Caulier

std::bad_alloc fix is in place for a few months. Closing now.
