Another typical memory overflow problem.

The execute trace before crash is

_decodeFirstFrame -> _decodeNextFrame -> _mad_frame_decode ->

_mad_layer_III -> _malloc -> ___heap_alloc

And application crash in the C line "stream->main_data =

malloc(MAD_BUFFER_MDLEN);":

int mad_layer_III(struct mad_stream *stream, struct mad_frame *frame)

{

...

/* allocate Layer III dynamic structures */

if (stream->main_data == 0) {

stream->main_data = malloc(MAD_BUFFER_MDLEN);

...

MAD_BUFFER_MDLEN is a macro, crash happens at malloc. malloc should be ok by

itself.

If add a printf line before that line:

int mad_layer_III(struct mad_stream *stream, struct mad_frame *frame)

{

...

/* allocate Layer III dynamic structures */

printf("mad_layer_III\n");

if (stream->main_data == 0) {

stream->main_data = malloc(MAD_BUFFER_MDLEN);

Crash will happen in printf. These phenomenons show there are un-expected

memory touch.

Then use bfin-uclinux-flthdr to increase stack size, crash disappear.
