  5:    PetscMPIAbortErrorHandler - Calls PETSCABORT and exits.

  7:    Not Collective

  9:    Input Parameters:
 10: +  comm - communicator over which error occurred
 11: .  line - the line number of the error (indicated by __LINE__)
 12: .  file - the file in which the error was detected (indicated by __FILE__)
 13: .  mess - an error text string, usually just printed to the screen
 14: .  n - the generic error number
 15: .  p - `PETSC_ERROR_INITIAL` if error just detected, otherwise `PETSC_ERROR_REPEAT`
 16: -  ctx - error handler context

 18:    Level: developer

 20:    Note:
 21:    Users do not directly call this routine

 23:    Use `PetscPushErrorHandler()` to set the desired error handler.  The
 24:    currently available PETSc error handlers include `PetscTraceBackErrorHandler()`,
 25:    `PetscMPIAbortErrorHandler()`, `PetscAttachDebuggerErrorHandler()`, and `PetscAbortErrorHandler()`.

 27: .seealso: `PetscError()`, `PetscPushErrorHandler()`, `PetscPopErrorHandler()`, `PetscAttachDebuggerErrorHandler()`,
 28:           `PetscAbortErrorHandler()`, `PetscMPIAbortErrorHandler()`, `PetscTraceBackErrorHandler()`, `PetscEmacsClientErrorHandler()`, `PetscReturnErrorHandler()`
