Removing all tons of symlinked fonts (those pointing to the /dosc/windows directory) fixes the segfault. Oh, now the possibly deciding factor: /dev/sda1 on /dosc type vfat (rw,noexec,nosuid,nodev,noatime,umask=000,quiet) IOW, providing a broken symlink into a VFAT partition (limited file attribute set or so?) may yield a successful crash. Thanks, Andreas Mohr

Which was making xfs not create its socket file due to it running unprivileged. (Closes: #579907) * Fix segfaults due to font open errors: - On error in open() set absbase to 0, so that openError() can be aware there's been an error. This happens usually on broken symlinks. Thanks to Edward Welbourne <[email protected]>. (Closes: #500724, #559142) - Handle mmap() errors, so that we don't end up accessing invalid memory. * Fix aborts when building with fortify support due to its bound checks.
