Segmentation Fault during Saving a PowerPoint Presentation in PPTX Format in C++

Meerkatpapa · July 8, 2023, 5:19am

I am using aspose slides (C++) to export pptx. When I save my pptx file using the “Save” function of “Presentation” class, I got the segmentation fault. The gdb backtrace is listed below:

Thread 238 "dummy::AsposePPTE" received signal SIGSEGV, Segmentation fault.

@Meerkatpapa,
Thank you for contacting support.

Please share the following files and information:

sample presentation file or other files if you used (you can zip the files and upload an archive here)
code example that reproduces the error
OS version on which the code was executed

Then we will check the problem soon.

@andrey.potapov Thank you for your quick reply.

I understand that the more information I give you, the quicker you will be able to resolve the issue. However, I am using aspose in some product so I am not allowed to leak any source code to anyone.

But, I am more than happy to explain the current situation: We use aspose to export some images along with their text explanations to a slide. When everything is compiled into a standalone executable and run on an online server, it works fine (meaning that aspose’s “Save” function works without any issue). However, when everything is compiled into dynamic libraries and linked by another binary, the aspose’s “Save” function produces segmentation fault when the binary launches. There is no guarantee that this binary is always run on the same machine as the standalone executable.

We suspect that the segmentation fault arises from font-related issues. I wonder, based on @andrey.potapov your experience and my explanation, if you can give me some hints or possible workarounds.

@Meerkatpapa,
Unfortunately, we need the files and information I mentioned earlier in order to reproduce the error on our end. Sorry, I don’t have enough information to help you.
