Tests failing under ARM; Unsupported syscall: 366

[Product Strategy Coverity Bug Uploader]

Seeing this failure under armhf on Jenkins, will attach a full log. We've found qemu to be flaky in some of these tests; this bug may serve as a placeholder if the cause isn't under our control.

Attaching indicator-session log, similar error.

[Allan LeSage (allanlesage)]

Apologies; I filed this bug in disguise.

[Francis Ginther (fginther)]

Also see this error signature when building lp:dee on arm with qemu.

[Allan LeSage (allanlesage)]

Having run a few test builds today, this no longer happens for indicator-session, marking 'incomplete' for that project.

[Alberto Mardegan (mardy)]

This affects libsignon-glib as well:

[Alberto Mardegan (mardy)]

If my investigation is correct, the syscall 366 is accept4(). This will be fixed with qemu 1.3, and a patch is already available here:

[Steve Langasek (vorlon)]

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
