[Bug 2015643] [NEW] General protection fault running multiple apt updates

[Ken Sharp]

Public bug reported:

Running the following command causes a segmentation fault:

$ schroot --all-chroots -- echo hello
hello
Segmentation fault (core dumped)

I tried a few times and it seems to have a couple of issues:

[277677.591948] traps: schroot[19714] general protection fault ip:7f5c4a95da2e sp:7ffd4c166540 error:0 in pam_cgfs.so[7f5c4a95b000+7000]
[277730.911628] traps: schroot[20740] general protection fault ip:7f772645f47e sp:7ffcb9d60610 error:0 in libc.so.6[7f77263e2000+195000]

Attached is a verbose log of the (original - an `apt update`) process.

Using a for loop is a workaround, but a massive pain (re: `apt update`):

$ for chroot in a b c d; do schroot -c "${chroot}" -u root -- apt
update; done
