We simply merged a collection of patches for Hare that adds a lot of good options for debugging Hare programs.
I want to introduce these features to you, and share a bit about what’s happening that makes them potential. Let’s take a look at some kinds of issues which invoke these new debugging features. Let’s start with a easy case: your program has an assertion failure.
We also detect quite a lot of different situations and print more useful data and a pleasant backtrace. Here’s one other example: stack overflow. We even have sign handlers for quite a few other situations, including segfaults, arithmetic exceptions, bus errors, and more, which provide an analogous backtrace and add helpful particulars about the specific nature of the problem.
This causes a segfault as a result of "main" is executable, however not writable. These options additionally make it easier to make higher use of Ember’s improved memory allocator, which checks for plenty of widespread reminiscence errors and aborts should they occur.
