forrtl severe (408) fort (19) Dummy character variable ...

Hi,

I have encountered a problem when porting fortran algorithm to C++.

The console has reported forrtl severe (408) fort (19) Dummy character variable 'TASK' has length 60 which is greater than actual variable length -3689***********

The calling code looks like this

SETULB(&n_, &m_, &param_.x[0], &param_.lb[0], &param_.ub[0],

        &param_.constraints[0], &f_, &g_[0], &factr_, &pgtol_, &wa_[0],

        &iwa_[0], &task_[0], &iprint, csave_, lsave_, isave_,

        dsave_, 60, 60);

where    char task_[60];

And the fortran routine looks like

subroutine setulb(n, m, x, l, u, nbd, f, g, factr, pgtol, wa, iwa,

     +                 task, iprint, csave, lsave, isave, dsave)

 

      character(60)     task, csave

      logical          lsave(4)

      integer          n, m, iprint, 

     +                 nbd(n), iwa(3*n), isave(44)

      double precision f, factr, pgtol, x(n), l(n), u(n), g(n),

c

c-jlm-jn

     +                 wa(2*m*n + 5*n + 11*m*m + 8*m), dsave(29)

The code breaks at

 if (task .eq. 'START') then ...

Could anyone give some instructions on how to solve this problem? By the way, I'm using Visual Studio 2010 for C++ compiler
