gEDA now requires guile 1.8.x, and as far as I know, all gnetlist backends have been fixed to work with it. The FAQ entry referring to bugs against Guile 1.8.X is probably out of date, and a red-herring.
This bug "probably" relates to a back-end which has poor recursion practice, and ends up using a lot of execution stack to produce the netlist for a complex design. You will need to know which specific backend, and which design - was used in order to confirm / deny whether this bug still exists. (I recall "some" backends have been improved to use less stack space.) -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
