We have no idea. Most bugs are never reported; people blame themselves = and try a different approach, or just blame Emacs in general.

The post-hoc probability is 1 because a user was affected by and = reported the bug, but that's not the point: the erroneous simplification = GCD(x, 0) -> x leads to trouble later on, as the report shows.
