Dear Fellow speech-tools maintainers, I just became aware of this bug ten minutes ago after reading Matthias Klose's email to debian-devel-announce.
The error log shows that the build failure is in esd which is no longer built in our git master. In the next 24 hours I will update my sid image and try building git master with gcc 4.8. Will update you all in the next 24 hours. best regards, Peter Drysdale
