No worries. I just did a repeat build on it, not with sbuild, but in a cloned chroot, and it built successfully. So it looks like whatever it is, it's somewhat intermittent. I would suspect GCC; unlikely to be hardware. I'll try doing a binary-only NMU build with sbuild (รก la the buildds), and if that also succeeds, I'll upload it. If I can reproduce the failure, I'll see if I can dump the preprocessed source and make a testcase; but given the elusive nature of the bug this might not be possible. Regards, Roger -- .''`.
