    I'm running my (use space)application on kernel complied with debug
    option.
    So whenever any user level program recevies segfault , kernel prints
    Register dump at the time of Segfault having values like PC etc.
    And program terminates.
    But recently i observed strange situation , while executing perticular
    function in my code ,
    kernel goes on printing register dump in while(1) loop .
    And process continues exicution.
    So what can be the possible reason ?
    What are other conditions in which kernel dumps register values ?
