decompression error: premature end of input
RedBoot>
But if I change 'gzip_close()' as follows:
case Z_OK:
#if 1
if (stream_end) {
break;
}
#endif
// Decompression didn't complete
p->msg = "premature end of input";
// fall-through
(i.e. I add the code inside the '#if 1' construct), it appears to work
correctly. I suppose I could go and chase down where the "-s" information
gets recorded and see if that is what gets passed to the decompress
function, but you asked if "-s XXX" solved the problem and the answer
appears to be "not yet".
