Hello support-team and community,

 

we developed a plugin for Adobe Illustrator 2018 and now adapted and compiled this plugin for Illustrator 2020 (24.3 64-bit), using the latest 2020-SDK and Visual Studio 2017.

 

After compilation, everything works fine under Windows 7 professional.

But under Windows 10 Illustrator crashes every time our plugin tool is used on the elements of a ring (compound path) consisting of "fills".

Please see the attached screenshot.

 

The crash always happens, when the function sAIPathStyle->GetPathStyle is called for the elements of the compound path.

The debugging shows the Error-Message:

Exception triggered by 0x00007FF6D8A85828 in Illustrator.exe:

0xC0000005: Access violation reading at position *some memory address*

Please also see the attached screenshot.

 

Unfortunately, I cannot debug into the function sAIPathStyle->GetPathStyle and therefore I do not know at which point exactly the exception occurs.

Is there some kind of debug-output functionality for adobe-functions which shows further information?

 

If someone has an idea about the cause of this exception and why only under Windows 10 and compound paths, I would be grateful for every help.

Thank you very much in advance.

 

System Data:

Windows 10 Pro 64-Bit

AMD Ryzen 7 2700X 3.80 GHz

NVIDIA GeForce GT 710

 

 

 

Update 24.09.2020 - Problem solved!:

The crash of Illustrator 2020 under Windows 10 was caused by casting-operations.

The following simple example works fine under Windows 7 but leads to a crash under Windows 10:

AIPathStyle pathStyle;
AIBoolean hasAdvFill = false;
AIArtHandle testArtHandle = art;
sAIPathStyle->GetPathStyle(testArtHandle, &pathStyle, &hasAdvFill);
unsigned long artHandleAsLong = HandleToULong(testArtHandle);
testArtHandle = (AIArtHandle)ULongToHandle(artHandleAsLong);
sAIPathStyle->GetPathStyle(testArtHandle, &pathStyle, &hasAdvFill); //Crashes under Win10

The same goes for the following example:

AIPathStyle pathStyle;
AIBoolean hasAdvFill = false;
AIArtHandle testArtHandle = art;
sAIPathStyle->GetPathStyle(testArtHandle, &pathStyle, &hasAdvFill);
unsigned long artHandleAsLong = PtrToUlong(testArtHandle);
testArtHandle = (AIArtHandle)ULongToPtr(artHandleAsLong);
sAIPathStyle->GetPathStyle(testArtHandle, &pathStyle, &hasAdvFill); //Crashes under Win10

To solve this problem, the datatype "uintptr_t" has to be used:

AIPathStyle pathStyle;
AIBoolean hasAdvFill = false;
AIArtHandle testArtHandle = art;
sAIPathStyle->GetPathStyle(testArtHandle, &pathStyle, &hasAdvFill);
uintptr_t artHandleAsUintptr = reinterpret_cast<uintptr_t>(testArtHandle);
testArtHandle = reinterpret_cast<AIArtHandle>(artHandleAsUintptr);
sAIPathStyle->GetPathStyle(testArtHandle, &pathStyle, &hasAdvFill); //Works fine under Win7 and Win10

Hopefully, this helps people having trouble with Illustrator 2020 and Win10.

Best Regards,

Fabian T.
