+ps segfaults with qemu-{arm,armel,mips,powerpc}-static
+
+Host: Ubuntu Precise AMD64
+Guest: Debian Testing armhf
+
+After running a debootstrap for Debian testing/armhf and entering the chroot, simply running "ps" causes a segmentation fault.
+
+$ sudo qemu-debootstrap --arch=armhf testing armhf http://ftp.uk.debian.org/debian/
+[...]
+$ sudo chroot armhf
+# ps
+Signal 11 (SEGV) caught by ps (procps-ng version 3.3.4).
+/bin/ps:display.c:59: please report this bug
+
+I couldn't find a bug report for procps, which would be unusual if such a bug existed, so I'm assuming the bug is in qemu.
+
+Unfortunately trying to run debootstrap for an Ubuntu variant fails to find the release file.
+
+ps is used a lot, as you can imagine, but specifically it fails when trying to install some packages via "apt-get install" and no attempt is made to recover.

+Signal 11 (SEGV) caught by ps (procps-ng version 3.3.4).
+/bin/ps:display.c:59: please report this bug
+
+I suspect this is a NULL pointer access that happens in procps where it isn't handling an error path that it's not expecting somehow (either a syscall we're not implementing, or perhaps something like /proc not being mounted in your chroot environment, or something about qemu's emulation of some file in /proc isn't right). The next stage would be to debug where exactly ps is crashing (attaching a debugger to the qemu gdbstub is probably easiest, or good old printfs...)
+
+
+Version: 1.6.0+dfsg-2ubuntu4
+
+This is fixed in Trusty in the qemu package. Doesn't look like qemu-linaro has been updated for Trusty. I don't know what is going on with these two packages.
+
+Tested ps in a bunch of arm* mips* and powerpc chroots with a Jammy host to check and it seems fine.
+
+Releases above are EOL, so can assume fixed. qemu-linaro is no more.
