#3547: Valgrind finds errors into compressed_matrix serialization

     Type:  Bugs                        |      Status:  new    
Milestone:  Boost 1.41.0                |   Component:  uBLAS  
  Version:  Boost 1.40.0                |    Severity:  Problem
 Keywords:  uninitialised bytes memory  |  
----------------------------------------+-----------------------------------
 I tried to write a compressed matrix to an archive and to re-read it from
 the archive.[[BR]]
 Without valgrind, the program seems to run correctly, but, if run with
 valgrind, it outputs some errors.[[BR]]
 [[BR]]
 I attached the source code and the valgrind output.[[BR]]
 I ran valgrind with this command:
 {{{
 valgrind ./compressed_mtx_ser test.arch >& valgrind.out
 }}}

 It seems that the serialization function tries to write not itialized
 bytes to file.
