Description Sebastian Dröge (slomo) 2009-09-05 09:00:14 UTC

Hi,
while adding gobject-introspection support for the GStreamer CDDA library I noticed that it's impossible add custom code before g_irepository_dump() is called from the autogenerated dump application.

For the case of GStreamer I need to be able to call gst_init() before any other GStreamer function.

Without this the dump application segfaults because it accesses uninitialized stuff.

Comment 1 Sebastian Dröge (slomo) 2009-09-05 09:01:28 UTC

Just for completeness, the backtrace of the dump application (gst_value_table is initialized by gst_init()):

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff620c2ff in gst_value_deserialize (dest=0x7fffffffc2c8, 
    src=0x608614 "BYTE_ORDER") at gstvalue.c:3419
3419	    len = gst_value_table->len;
(gdb) print gst_value_table
$1 = (GArray *) 0x0
(gdb) bt

+ Trace 217338
