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?

Zhao Liang,
I remember we meet the same issue before. Could you check? Shi Ling Tel:86-10-84733539 Motorola (China) Technology Ltd.

I had the same issue. I manually modified gstconfig.h to make it work. Glib is out of my control.

Another walkaround is changing configure.ac, disable printf extension support.
