[petsc-users] PetscFinalize()

[Barry Smith]

    This error occurs if more than 250 functions are registered with PetscRegisterFinalize(). Under normal usage that should never happen. 

    Likely something is calling PetscRegisterFinalize() unprotected, that is, calling it many times with the same function to register. Likely this is in SLEPc. 

    The other possibility is some strange interaction with .dll on Microsoft Windows?   

    First I would start your program in the debugger, put a break point in PetscRegisterFinalize() and then run the program. Each time it breaks in PetscRegisterFinalize() note where it is called from. Under normal circumstances PETSc should call 
PetscRegisterFinalize() around 10 times.  If you see it called 30 times note what functions are calling it over and over again and send back that information.
