Up until yesterday, my AEC-to-WebAssembly compiler was, if somebody tried to use two structures of different types as the second and the third operand to the `?:` (ternary conditional) operator (which is always wrong, but it has happened to me quite a few times that I accidentally tried to do it in C++), as in this example:
For that example, my AEC-to-WebAssembly compiler was outputting this error message:
Truly absurd, right? There are no arrays in the program, so how can a part of a compiler possibly request an array with a negative size? It took me hours to figure out what is going on in my compiler (Which perhaps shouldn't be surprising considering that I wrote it 3 years ago.).

For that example, my AEC-to-WebAssembly compiler was outputting this error message:

Code:

I have made a forum thread about how to speed up the tokenizer,

Parsing the program...

Compiling the program...

Truly absurd, right? There are no arrays in the program, so how can a part of a compiler possibly request an array with a negative size? It took me hours to figure out what is going on in my compiler (Which perhaps shouldn't be surprising considering that I wrote it 3 years ago.).

It took you hours to resolve a mistake you made three years ago in your compiler? I foresee a great future for you as a programmer.

Well, there were actually two bugs that are triggered by that code, one in the core of the compiler and one in the semantic analyzer. It would have probably taken me significantly less time if I knew how to use a debugger. But compilers are among the most complicated pieces of software, perhaps only less complicated than operating systems.

Well, they didn't teach us that at the university, and I haven't bothered to learn it in my free time.

I would be deeply concerned if a programmer I was interviewing hadn't bothered to learn how to use a debugger, and if asked why, and this was the answer...

...even more so if he told me he rather bothered others with his linguistics BS.

And what kind of university doesn’t include debugging in a COMPUTER SCIENCE course?? Big Lou’s House O’ Data?
