[Bug fortran/43205] -finit-local-zero and -fno-automatic used together with large 2-dim variables take too long to compile

[burnus at gcc dot gnu dot org]

------- Comment #2 from burnus at gcc dot gnu dot org  2010-02-28 14:05 -------
CONFIRMED. For zero initialization, the created dump should look like:
  static integer(kind=4) variable(100000) = {};
rather than
  static integer(kind=4) variable(100000) = {0,0,0,0,0,0,........,0,0};

I think as workaround one can simply leave out the -finit-local-zero as static
variables are always zero initialized. And with -fno-automatic one should only
have static variables.

For the example in comment 1: This is not a real regression as before the data
was not properly handled. I filled now PR 43210, which is one way out. (Thanks
Dominique for the suggestion.)
