When Exceptions Collide: Managing Errors in ArangoDB
Managing Exception Collisions | ArangoDB BlogThis is a story of an excursion to the bottom of a deep rabbit hole, where I discovered a foot gun in `gcc`’s `libgcc`. The investigation has cost me several days and I hope that by writing this up I can entertain others and save them the journey.
