This has built fine on Debian.

(retried once, it persisted)

[Timo Jyrinki (timo-jyrinki)]

Same source built in Debian two weeks ago even for armhf, so maybe gcc-6 6.3.0 is related.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Timo Jyrinki (timo-jyrinki)]

Continues to be a problem with forced use of gcc 6.2.1-5ubuntu1 and binutils 20161212 ubuntu version:

https://launchpadlibrarian.net/301204319/buildlog_ubuntu-zesty-armhf.qtwebkit-opensource-src_5.7.1+dfsg-1build1~1_BUILDING.txt.gz

The forcing was done with aid of version bumped older versions at https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/2332/+packages

However with Debian variants of roughly those versions of gcc-6 and binutils a build of the identical qtwebkit source succeeded on December 16th: https://buildd.debian.org/status/fetch.php?pkg=qtwebkit-opensource-src&arch=armhf&ver=5.7.1%2Bdfsg-1&stamp=1481858819

Looks like workaroundable by not using gold on armhf either for Qt (already disabled on powerpc and now newly i386 in Debian).

[Timo Jyrinki (timo-jyrinki)]

See bug #1654820 too. Ended up disabling gold on 4 of 6 architectures.

[Timo Jyrinki (timo-jyrinki)]

..4 of 7.

[Matthias Klose (doko)]

not addressing for gcc-6
