+Subject: [PATCH] gst_private.h: increse padding in struct _GstClockEntryImpl
+
+When compiling for 32bit architectures with 64bit time_t e.g. riscv32,
+the static assert that the GstClockEntryImpl smaller or
+equal to the struct _GstClockEntryImpl triggered.
+(they were 12bytes off).
+
+To fix this, the padding is increased by 8 bytes (on 32bit).
