#2195: [uBlas] compressed_matrix::erase_element() segfaults
----------------------------------------------+-----------------------------
 Reporter:  Niko Vuokko <niko.vuokko_at_[hidden]>  |       Owner:  guwi17 
     Type:  Bugs                              |      Status:  new    
Milestone:  Boost 1.35.1                      |   Component:  uBLAS  
  Version:  Boost 1.35.0                      |    Severity:  Problem
 Keywords:  compressed_matrix erase_element   |  
----------------------------------------------+-----------------------------
 The following example segfaults, system is GCC 3.4.4 on Cygwin, Boost
 1.35.0.
 {{{
 compressed_matrix<int> m(2,2);
 m(0,0) = 1;
 m.erase_element(1,0);
 }}}
 The problem is that inside erase_element std::lower_bound oddly returns
 it_begin, even though simple
 {{{
 while(*itt < elem2)
    ++itt;
 }}}
 returns it_begin+2.
