DSI error at exit

Hi all,

I have created a function to handle a memory list.
I can create the list, use it ... no problem.
But, if I use the function to remove the memory allocation (when leaving AmiDARK Engine application), I get a DSI crash.

Here is how I create a new list using this function :
MyPTR = UpdateImagesLists( 32, MyPTR, 0 );

Here is how I add 32 new entities to the list :
MyPTR = UpdateImagesLists( ActualPTRSlots + 32, MyPTR, ActualPTRSlots );

Here is how I remove the list from memory :
MyPTR = UpdateImagesLists( 0, MyPTR, ActualPTRSlots );

Here is the function :


MyAllocVec & MyFreeVec for correctly. Here are the functions :


Do someone understand why ?

Kindest Regards,
AmiDARK

Way not compile whit -D__USE_INLINE__

gcc my_prog.c -o my_prog.exe -D__USE_INLINE__

no more "IExec->" or "IDOS ->" etc.

I'd prefer this because it forces me to keep an eye on which functions I use because between AmigaOS4, MorphOS & older AmigaOS, sometimes, functions args are not the same ...

@Freddix:

1. Please the [ code ] tag when posting code, it makes much easier to read.

MyewImagelist appewars to be a pointer to void, so will be size 4 bytes, is that what you want?

@BroadBlues :
Yeah, sorry forgot the tag :(

Concerning the void, I've already replaced the sizeof ... with 4 but I got the same result ...

@Since I don't know what's in the rest of your code, I can only suggest a couple of DebugPrintF() statements to see if the memory address (pointer) you get when you allocate the memory is the same as when you free the memory. If the pointer accidently gets altered, incremented or decremented in between that might produce a DSI error.

@freddix

A crashlog could help. If the DSI is within your code at least you'll know the reason of the crash.

@Xenic :
Pointer is the same after created and just before release ...

@CentaurZ :
Here is the crash log :

I don't know how to use it to know where the crash is.
One thing I can say is that if I put in // the line that call the function to release the memory bloc, I do not get the DSI error ...

@freddix

It looks like you are passing a NULL pointer to some function from minigl.library in DEDeleteImage() (the cause of the DSI is an access to 0x00000020). Now you have to find out why.

You can use Chris Youngs addr2line-ARexx.-script: http://aminet.net/package/dev/debug/addr2line



This should get you the correct sourcefile and line.

@All :

Thank you :)
I freed the memory that handle gl image ID before deleting images in my Image's Destructor() function.
Now fixed.

More to this, your informations helped me understand a bit more the crash log file. This may help me in future crash/issues :)
