They might still work. gcc is now configured to target 586 and above, but I don't think there are any 586-only instructions that it will automatically generate. However, given that this fatal bug has not (so far as I know) been reported in the 5 years since it was introduced in unstable, I suspect you're one of a very few people still using Debian on a 486, and you may find many other things broken.
