Since Sarovar is dead: Where is the pdftex bug database now?
It has never been used, but there are (too many) trackers at
https://foundry.supelec.fr/projects/pdftex.
I guess just use "Bugs". I think I just set that up to email reports to
ntg-***@ntg.nl.
Various people said they would import the data from sarovar, but it has
never happened, and as far I'm concerned it'll be a happy surprise if it
ever does. -k
