This reminds me of how ~25 years ago I wrote little C macro library to perform safe (non-overflowing, and/or saturating) integer arithmetics and comparisons, however the small application I wanted to use it in had the compiler crash after 2-3 hours due to insufficient RAM+swap when compiling a single source file using those macros. It turned out the macro expansions made the translation unit grow to GB size, which must have been 4-5 orders of magnitude over its original size.
