[petsc-users] possible error

[Nachiket Gokhale]

I am getting the error at the end of the email only in optimized mode.
Output of -on_error_attach_debugger and "where"  is at the end of this
email.  Running through valgrind in debug mode doesn't show up any
memory misuse on my part.  Does this seem to be something in petsc?
