Package: qemu-system-arm Version: 1:2.11+dfsg-1 Severity: grave Dear Maintainer,
I just got an nbdkit build failure from the armhf autobuilders. The test-suite uses libguestfs and spawns qemu-system-arm which is killed by SIGSEGV. Please see https://buildd.debian.org/status/fetch.php?pkg=nbdkit&arch=armhf&ver=1.1.28-1&stamp=1516723989&raw=0 for the build log. I re-ran the check in an armhf porterbox chroot (abel) and got the output below. I don't see any useful output after starting qemu-system-arm, but at least the command line parameters are visible. ,---- | $ LIBGUESTFS_TRACE=1 LIBGUESTFS_DEBUG=1 make check | [...] | guestfish -N fs
