hello, i have a problem which i don't know how to handle:
i have a nonlinear solver class with a public solve(..) function and a private createProblem() function. In createProblem() i define the functions and forms, a, L. when i call newtonsolver.solve(*this, uu->vector()) inside createProblem(), just after creating the forms, all is fine. when i call newtonsolver(*this, uu->vector()) inside the other class function solve(), i get a segmentation fault as Created solver Created Problem Starting Newton solve. Program received signal SIGSEGV, Segmentation fault.
