Just implementing -isEqual:, never invoked, causes crash

I implemented an -isEqual: method in one of my classes today. This causes the app to crash while loading a document, after some milliseconds. Crashes occur in different unrelated places.

I then simplified the implementation to just log and call super --

- (BOOL)isEqual:(Browfile*)otherBrowfile {
    NSLog(@"isEqual???") ;
    return [super isEqual:otherBrowfile] ;
}

Or, return a constant --

- (BOOL)isEqual:(Browfile*)otherBrowfile {
    NSLog(@"isEqual???") ;
    return NO ;
}

Crashes either way, and the log statement in there never logs.

Simply removing this implementation by renaming it to XXisEqual: results in no more crashes. The crash looks like a memory-smasher, but under the circumstances maybe something is being linked incorrectly. I "touched" all of the files and re-built, and did not get any "multiple implementations -- using this one" warnings.

I've implemented -isEqual: in several other of my classes with no problems. What in the world could do this?

Please make my day by giving me ^something^ to chew on here.
