    initial v1  
    11I think here it's a bug in TextSearch, in Grepper.cpp.
    2 The line buffer handed to sscanf() to extract the filename, line number and position is sized to B_PATH_NAME_LENGTH * 2.
     2The line buffer handed to sscanf() to extract the filename, line number and position is sized to B_PATH_NAME_LENGTH * 2. Which gives only 2048 max, AFAICT.
    33
    4 If the line read from grep output is longer than that, I fear that there is no \0 at end, which lead to sscanf() stepping outside memory boundary and therefore crash.
