[petsc-users] ask for the ERROR MESSAGE

[Barry Smith]

  This is an inconsistent error message. It prints

> Error in query to SYEV Lapack routine 0

  But the error check is on lierr != 0 so the error check should not have been triggered. I inspected the code and there is no obvious problem with mixing up different-size integers; the prototype for the function expects a PetscBlasInt, and that is what is passed in. Strong compiler optimizations are not turned on so it seems unlikely it is due to a compiler bug.

  Are you familiar with debugging? You can use the command line option -start_in_debugger type cont in the debugger windows, and when the debugger stops with the error, you can type bt and look around at the variables to see if any look off.
