Zhao Liang,
I remember we meet the same issue before. Could you check?

I tracked down the cause of this to an incompatibility with my build of glib.
When cross-compiling glib, it decided to not like glibc's printf (because it
tried running some printf tests and failed, because it was cross-compiling),
and thus went and used its own printf implementation.
Gstreamer was not aware of this decision in the glib build though, so it
happily went ahead and used glib assuming it had a glibc printf that could
support printf extensions (that it uses to format %P in strings).
Rebuilding glib with the right configure cache settings (below) solved the
gstreamer crash.
glib_cv_long_long_format=ll
ac_cv_func_printf_unix98=yes
ac_cv_func_vsnprintf_c99=yes
So this solved the problem, but I'm wondering if there should be a better way
for gstreamer to detect if it is safe to use %P or not: not only does glibc
need to provide it, but glib needs to be using it too.
Or is the fact that glibc provides it enough proof that glib should be using it
and anything else is a broken setup like mine was?
TIA,
Bernard.
