Termination code 139

[Gyorgy]

Hi,

I have a nonlinear solver written in C++ interfaced to AMPL. I get the following error message after running it:

"error running ./mynonlinearsolver:

termination code 139; core file written"

However the code does terminate and gets the correct results but somehow at the very end I still have this error message my write_sol() function looks the following:

"write_sol(char* msg, double* x, NULL, NULL);"

The "msg" will actually print. However when I type 

"display x;"

it will display the starting point, but when I check separately the x pointer does point to the correct solution so somehow the x pointer I'm passing to write_sol() doesn't make it into the .sol file. Could this be because I'm using a double* instead of real*?

Any help is much appreciated!

Best,

Gyorgy

Hi Gyorgy,

"termination code 139" means segmentation fault. It is hard to say what is causing it in this case without looking at the actual code. It is possible that x array is not large enough.

I suggest building a debug version of the solver and running it under a debugger to see where exactly the segfault occurs. Or post the source code of your solver interface or at least a part of it that shows how you allocate x, msg and call write_sol.

HTH,

Victor

Hi Victor,

thanks a lot for your response the segfault was enough information to fix the issue!
