 From the reporter (Круглов Сергей <skruglov at nm.ru>):

 * First bug I detect with attempt write file to full device (zero empty
 blocks).
 * And after I send too many files, disk overflow and system not responding
 (receive and write to disk have high priority). A test, and found block=0,
 after -- = too big value.
 * In imfs_memfile.c
 function IMFS_memfile_extend
 block declared: unsigned int   block, and after block— work incorrect (if
 block = 0).
 for ( ; block>=old_blocks ; block-- ) {
   IMFS_memfile_remove_block( memfile, block );
 }

 Must be declare int block;
