I'm running julia version 1.10.0 on fedora core 38. After running the example code

>> jlcall('sort', {rand(2,5)}, struct('dims', int64(2)))

I obtain the following

Hi, I had the same error and it turned out to be a Matlab issue: https://fr.mathworks.com/matlabcentral/answers/321256-system-command-gives-segmentation-fault
I solved it by changing the system commands in jlcall.m to:

[st, res] = system(['source ~/.bash_profile; ', cmd]);

I'm sure there is a more robust solution but it worked.

Thanks for looking into this! That's very odd, but I have seen issues in the past with Matlab and environment variables. Somewhat confused why sourcing .bash_profile fixes your issue, but if it works for OP too then I'll close this.
