Furthermore,
Finally I also found the real reason of the crash in the first email.
It is my own fault: the last variable, lambda, as the Lagrange multiplier is
also required with a branch in init_value(). Since there is a call to
a function pointer to lambda, definitely there is an error.

Dear John,
Thank you for your kind help.
At least I got one way, just as a temporary solution:
I set a global string outside everything, namely, std::string project_var, then
in the function
Number init_value (const Point& p,
const Parameters& parameters,

Hello,
I wrote a class for set up initial values and called it by
system.attach_init_function (init_sys);
Here is the part of init_sys
void init_sys(EquationSystems& es,const std::string& system_name)
{
System & system =
es.get_system(system_name);
vector< string >
