------- Comment #2 from burnus at gcc dot gnu dot org  2007-02-20 15:54 -------
Thanks for the report. I can confirm that it happens with 4.1.x (4.1.2 20070115
[SUSE Linux]); note however that the ICE does not occur with gfortran 4.2 and
4.3.

I'm not sure whether we have the resources to fix it in 4.1.x, though :-(
In any case, daily gfortran 4.2 and 4.3 trunk/branch builds are available from
http://gcc.gnu.org/wiki/GFortranBinaries

The segmentation fault is (using SUSE's gfortran-4.1) due to an 
==29696== Invalid read of size 8
==29696==    at 0x41B992: (within /usr/lib64/gcc/x86_64-suse-linux/4.1.2/f951)

------- Comment #3 from fxcoudert at gcc dot gnu dot org  2007-03-03 09:57 -------
Confirmed, but unless it's a regression for gfortran-4.0, it won't be fixed on
the 4.1 branch. It's already fixed on 4.2 and above, and it's not a regression
wrt g77.
