Hi all.I am getting a weird run time crash with some fbx file when build my app with vs2010 in debug mode. I upgrade the ImportScene sample to vs2010 and get the same error:

----------------------------------
debug assertion failed
file: ....\vs2010\vc\include\xstring Line:1441
Expression: string subscript out of range
-------------------------------------------

Call stack shows this error occur in the KFbxImporter::Import() funcion:

Every things works fine under vs2008, so i guess maybe it’s a bug in vs2010 lib. I uploaded one of my test files which may cause this problem(a lizard model comes from a ms xna sample).
Thanks for any help!

Crashes for me too.

Looks like the same bug I sent in a little while ago:

  FBXViewer.exe!fbxsdk_2011_3_1::KFbxImporter::Import()  + 0x32 bytes C++

Here is the response:

Yes, I can reproduce it (only) on VS2010, which means it’s good on VS2005/2008. It seems FBX sdk hit an assert of xstring as bottom picture.

We have logged this issue in our bug-base(#373685). Our developers will investigate it as soon as possible. Thank you for your info.

Bump

This is still an issue in version 2012.1, although it seems less likely for files using format 7.1.0 or later.

Any ETA on a fix?

Hi,

This issue is marked as fixed on our side, for FBX SDK version 2012. The file used was named “FailsToImport.fbx”. JoevdH, do you have a FBX file that illustrates this bug?

The lizard.fbx file attached to the OP still shows this issue.

I’ll reopen the issue with the lizard file.
If you have additional files, we’ll add them to our bug database for testing.
I’ll keep you posted.

Hi,

The issue is now fixed on our side, and the fix will be available in the next version of the FBX SDK.

FYI, the assertion is caused by VS2010 xstring to be more strict in its tests for the index of the operator []. Apparently, it is not allowed anymore to access the null character (backslash, zero) with a call like buff[index] where index = strlen(buff).

I don’t have an ETA for the next version, sorry.

Thanks
