Fortran left broken for a couple of days now

[Steven Bosscher]

Honza,

Your patch here: http://gcc.gnu.org/ml/gcc-patches/2005-06/msg00976.html
has left a number of fortran test cases broken (e.g. gfortran.dg/select_2).

The problem seems to be that you used the aux field as a replacement for
rbi->copy_number, but tree_verify_flow_info assumes aux is cleared before
it is called (see the SWITCH_EXPR case, "gcc_assert (!label_bb->aux ....)").
You must have seen this if you tested your patch with checking enabled, the
patch broke fortran on all platforms.

Can you please fix this? (It is also http://gcc.gnu.org/PR22100)

Gr.
Steven
