Bug#667596: gtk_init gives bus error on mipsel

[Enrico Tassi]

Package: libgtk-3-0
Version: 3.2.3-1
Severity: important

It seems gtk is completely broken on mipsel. lua-lgi FTBFS on mipsel, and 
its author (Pavel Holejšovský) figured out that it is enough to call gtk_init
to get a bus error.

Interestingly enough all gtk packages are installed on eder, so maybe someone
is already debugging this.  But I could not find an open bug report on the
subject.

$ ssh eder.debian.org
$ dchroot unstable
$ cat > a.c
#include <gtk/gtk.h>
int main (int argc, char **argv)
{
  gtk_init (&argc, &argv);
  return 0;
}

$ gcc a.c -o gtktest `pkg-config --cflags --libs gtk+-3.0`
$ ulimit -c unlimited
$ xvfb-run ./gtktest 
Bus error (core dumped)
$ gdb ./gtktest
...
bt
