Hi,
I have the strange Situation that I get a segfault in debug mode also
the program is working in optimized mode.
Has anybody an idea what might cause this behavior ?
The gdb gives me the following stack backtrace:
Program received signal SIGSEGV, Segmentation fault.

It seems whhat ever happens is linked to the constructor of my Dynamics
class.
template< int dim>
Dynamic<dim>::Dynamic( double dyn_duration,
double strobe_time,
double step_time,
DoFHandler<dim> const & dof_handler_deform
)
:
dof_handler_dyn_def(tria),
dof_handler_dynamic(tria),
dof_handler_deformation (dof_handler_deform),
fe_dyn_def(FE_Q<dim> (1), dim),
fe_dynamic(2)
{
time_strobe=strobe_time;
time_step =step_time;
dynamic_duration =dyn_duration;
file_counter=0;
}
Thanks in andvance for your help.
