Confirmed. I need to understand what MIPS_DEBUGGING_INFO means - and why it is
not present in 4.4 - but maybe reverting it and suggesting in PR fortran/39791
to use 4.4/4.5 is be safer/better alternative. - Thanks for the report!

Stupid but working fix: Reverting the patch for PR 39791 on MIPS_DEBUGGING_INFO
only. I think that's the safest to do - even if it is not the most elegant way
of doing it. I don't like backporting Rev. 137975 which would be the proper fix
as one probably would need more modifications, risking regressions - and that
does not seem to be worthwile for PR 39791 on 4.3.x.

------- Comment #3 from jakub at gcc dot gnu dot org  2009-05-07 14:58 -------
This patch is correct.
Alternatively, you could define the dimension_number variable unconditionally
(remove #ifndef and #endif around it), initialize it to 0 and not initialize it
in for init expression.  For MIPS_DEBUGGING_INFO, dimension_number is never > 0
in the body of the for cycle in 4.4+...

Not really, see PR 40268 for description and proposed patch.

Confirmed fail on cross to alpha-linux-gnu.
