<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Asterisk was killed by SIGBUSes on Jeremy Kisters' Sparc.
One of the problems was that the STDIO file structures were getting misaligned because of some compatibility code.
A Mozilla bug report on the Debian tracker provides lots of useful info.

I added comments[1] in the asterisk.exports.in file so we wouldn't forget what that strange entry is doing there.
