internal compiler error: Segmentation fault

[ayush-agrawal]

I occasionally get the following error when using make. Any idea what might be causing this. I also recompiled all the functions in MATALB before running make.

We have seen this issue before. It has to do with the computer running out of memory when compiling the functions. Make sure to only compile one function at a time (not multiple in parallel). In other words, just use the make command. Not make -j8 or anything like that.

Also, make sure you are not running any other memory intensive programs when compiling. You may have to use a computer with a large amount of memory (it works on our 32 GB RAM laptops).
