The stack requirements have grown. This is standard.
dpkg had a bug filed against it; perl 5.6 was causing a regex to fail in
install-info, while perl 5.005 let it succeed. 5.6 was using more stack
space, and so hit the limit sooner.
The problem was the code, even tho it was technically correctly.
Of course, I don't know if kcj could be rewritten to not be so recursive, or
kaffe could be tweaked to use less stack space.
