Package: libxi6
Version: 2:1.4.3-3
Severity: important
Tags: upstream
On mipsel (Loongson 2F, Yeeloong), many programs (at least all programs
that use libgtk-3-0) crash with SIGBUS immediately when executed, e.g.:
$ gnome-terminal
Bus error
Same with gnome-calculator, gcalctool, epiphany and anjuta. I have
traced the problem to an unaligned access in libxi (see GDB output
below) and have made a quick patch to fix the bug.
(gdb) run
Starting program: /usr/bin/gnome-terminal
Program received signal SIGBUS, Bus error.
