The problem

The following code crashes Mathematica 12 for Windows 64 front-end reproducibly in my computer (Win7 Pro, i7-4770 3.4GHz 16Gb RAM).

 , Joined -> True
 , PlotRange -> {{0, 100}, {0, All}}
 , PlotStyle -> Directive[Dotted, Red]

I filled a bug report to Wolfram Support (CASE:4279741), but they came back to me saying the crash is not reproducible on their system. I have tried with fresh kernels and it does crash for me on Mathematica 12, but it doesn't crash in version Mathematica 11.3 (I don't have other installations to test)

I'm looking for help narrowing down the crash condition in different platforms.

Does this code crashes the front-end reproducibly in other systems?

I'm not looking for a way around, only for confirmation about the reproducibility of the crash.

Due diligence

I have done the following attempts to understand the source of the problem.

Fresh environment

I have deleted all the files and folders suggested by support to provide a fresh environment (docs). Still, it crashes all the same.



I have attempted to Trace the evaluation (using TraceToFile from this answer ), but annoyingly it doesn't crash inside TraceToFile.

The answer I needed was provided in the comments, but it could be a good idea to have a community wiki answer with some extra details people may want to add. Feel free to edit to add details.

  • Answer by Wolfram Support

Crashing conditions by platform

Crashes only observed in Mathematica 12.0 (so far).


Crashes on Wolfram Desktop 12.0 Linux x86 (64-bit) with 25k points, not 10k as in the question.


Wolfram Support claims it crashes "Sometimes", no user reports.


Crashes confirmed in 64-bit versions on Win 7, 8 and 10 with code in question. Not reproducible on Windows 10 32-bit

Answer by Wolfram Support [CASE:4279741]

Thank you for taking the time to send in your crash logs.

We were able to reproduce the crash on Windows, and Mac (Sometimes). I have forwarded my crash report file in an issue report to our developers with the information you provided. I also included your contact information in my report.

We are always interested in improving Mathematica, and I want to thank you once again for bringing this issue to our attention. If you run into any other problems with any of our products or have any additional questions, please do not hesitate to contact us.
