I am running Mathematica 12.1 on Fedora 36. When I try to export 3D plots as PDF files, Mathematica crashes. Using the Command Line to get an error log, I am simply reported the title of this post:

Cannot select: intrinsic %llvm.x86.sse41.pblendvb

I have LLVM version 14.0.5-1.fc36. I also installed LLVM-devel (the dev counterpart) to see if that helped, but nothing changed. This GitHub post seems to indicate it is a version mismatch, but I am not sure how I could go about fixing that. While this thread seems to indicate that opening a ticket is the way to go, I am using a Student licence handled by my university, so I am not sure how I to contact technical support. (Thank you, Domen, for pointing out to me how to send a ticket to technical support!)

To clarify, 2D plots export to PDF with no issue.


  • A minimal working example that crashes Mathematica: Graphics3D[Point[{0,0,0}]]. As pointed out in this thread, rasterisation bypasses this issue.
  • I have opened a ticket to technical support. I will give timely updates.

    $\begingroup$ Welcome to Mathematica StackExchange. Usually, crashes and other user/machine-specific troubles are difficult to be solved on StackExchange, and it is advisable that you contact Wolfram Technical Support. If you have a legitimate student licence, then you should have your license number or activation key (menu Help > About ...), which you should include in the report for the support. $\endgroup$

  • $\begingroup$ Welcome to the Mathematica Stack Exchange. You can leave this thread open and update it to include the bugs tag along with other details when you hear from support. In order for others to at least recreate the same error, please include a minimal example. Thanks. $\endgroup$

    $\begingroup$ As it stands this question is off-topic, and may be closed. However, to make it useful and avoid closure, you could edit the question and offer a minimum working example that reproduces the crash, and ask if this can be reproduced in other systems and versions. $\endgroup$
