Autopkgtest fail with glibc 2.34

[Simon Chopin]

The autopkgtests fail with glibc 2.34, while running them with the plain impish.

The superficial failure is that the script cannot find the expected window name. Looking into it, it appears that this might be caused by wmanager displaying an error popup instead of its main window. One possible reason for such popup is not being able to read the wmanagerrc file, which defaults in $HOME/.wmanagerrc (but the script sets it to a custom location in /tmp).

Next step will be to find out exactly the cause of the failure.

[Simon Chopin (schopin)]

Tracked down the failure which was due to an UB (uninitialized memory read) being exposed by the recent glibc changes, presumably something in the memory allocation area.

In any case the attached debdiff should fix the issue. You'll find a built version of the package in my PPA: https://launchpad.net/~schopin/+archive/ubuntu/test-ppa/+sourcepub/12662890/+listing-archive-extra
