	That is the gdb log ;(

	make distclean;./configure --enable-debug

./codec-cfg ./etc/codecs.conf > codecs.conf.h

	The values are slightly different but 's'  is still bogus:

		s=0x10000 <Address 0x10000 out of bounds>

	Oh, the last 10 lines that were written to codecs.conf.h are:

"RAW YVU9", /* info */
NULL, /* comment */
NULL, /* dll */
"raw", /* drv */
{ 0x00000000, 0, 0,{ 0, 0, 0, 0, 0, 0, 0, 0 } }, /* GUID */
0 /* flags */, 1 /* status */, 0 /* cpuflags */ }

	The file codecs.conf.h is quite large so something is being written
	out before the coredump happens:
