If "serial_source" has been typedefed to be a pointer,
which is what the subsequent usage tends to indicate,
then this _should_ allocate and init a block of whatever
rather than just a pointer. If that is the case then it
seems to be a poor naming choice. You'll have to chase
the dragon further up the tree to see what it really is...

Hi all,
I'm currently debugging strange error in serial forwarder (c version,
TinyOS 2.0.1), and I found this :
//////////////////
serialsource.c:273:
serial_source src = malloc(sizeof *src);
if (src)
{
memset(src, 0, sizeof *src);
src->fd = fd;
src->non_blocking = non_blocking;
src->message = message;
src->send.seqno = 37;
return src;
}
///////////////////
I think malloc(sizeof *src) will return pointer to 4-bytes allocated heap,
instead of pointer to sizeof(struct serial_source). So, src->non_blocking,
src->message, and src->send.seqno will point to memory that's not
belonging to this program.
Please correct me if I'm wrong.
Regards,
