Can you try getting the coredump via coredumpctl?

Can you try getting the coredump via `coredumpctl`?

I had to:

sudo -i
ulimit -c unlimited

Because for some reason, root had ulimit -c set to 0.

Here's a backtrace from that:

Maybe I need to dump the filenames of the installed packages, somehow.

strcmp in _alpm_sync_prepare seems to segfault. As far as I know that only happens if one of its args is not initialized.

0108e2c64e/lib/libalpm/sync.c (L472)

Maybe gdb can be used to dump the var content?

pkg2->filename is NULL.

*pkg2 is:

$5 = {name_hash = 5737442551468256197, filename = 0x0, base = 0x0, name = 0x5612278331f0 "libaccounts-qt",

  base64_sig = 0x0, arch = 0x0, builddate = 0, installdate = 0, size = 0, isize = 0, download_size = 0,
  handle = 0x5612264d9020, licenses = 0x0, replaces = 0x0, groups = 0x0, backup = 0x0, depends = 0x0,
  optdepends = 0x0, checkdepends = 0x0, makedepends = 0x0, conflicts = 0x0, provides = 0x0, removes = 0x0,
  oldpkg = 0x0, ops = 0x7f5b1f406060 <sync_pkg_ops>, files = {count = 0, files = 0x0}, origin_data = {

  reason = ALPM_PKG_REASON_EXPLICIT, scriptlet = 0, infolevel = 0, validation = 0}

Attempting to sync it with the v3 repo enabled results in:

I removed libaccounts-qt-1.16-3.1. Should be rebuild within the next cycle. Can you try syncing after 3.1 is gone from the repo? (should be momentarily, as soon as the mirrors sync up)
