I'm getting a segmentation fault when compiling. I've tried my usual techniques to overcome the problem such as - waiting till the next day and/or complete refresh. All to no avail. I've been compiling for several years without major incident. Last compiled successfully on July 6th 2018. Have I missed something that I should have done recently to cater for some change. I'm not aware of other people encountering this problem. Should I raise it as a bug?
