[petsc-users] upgrading to 3.22.4

[Barry Smith]

    I have just pushed a major update to the Fortran interface to the main PETSc git branch. Could you please try to work with main (to become release in a couple of weeks) with your Fortran code as we debug the problem? This will save you a lot of work and hopefully make the debugging more straightforward.

    You can send the same output with the debugger if it crashes in the main branch and I can try to track down what is going wrong.

Note the program starts normally and i can do stuff with the interactive interface for the code -- even plotting the mesh etc. so I believe the input data has been read in correctly.  The crash only occurs when I initiate the formation of the matrix.
