If saying "circular symlink madness" you refere to the fact that
programs 
segfault when dealing with circular symlinks (chains of symplinks
pointing 
back to themself), then it is worth to have a look to bug#20426, in
which
I found the lines of glibc where the bug is.

I don't have a fix for it (it's a bug in the design of the function).
That function should be rewritten or patched adding a counter to stop 
following the symlinks.
