--- Comment #7 from Sebastian Dröge (slomo) <slomo at coaxion.net> ---
The first backtrace is for a different crash than the second. Can you check the
address of meta and meta->pts in the second backtrace? In theory meta should be
properly aligned, it is allocated with g_slice_alloc() in
gstbuffer.c:gst_buffer_add_meta.

For the first one, a new backtrace would be needed but the registry
serialization/deserialization code tries to keep alignment correct everywhere.
There might be places where that is not done correctly though.
