doesn't fail in 4.4.0 and 4.3.1.
Since this refers to an 'old' version of trunk (i.e. 4.4. in full development),
I'll close this as fixed. If the problem remains with an up-to-date  trunk, or
on any active release branch, please reopen.

Joost,

Did you test on the solaris machine or on the i386 machine. I think this is a
architecture specific bug. Could you please confirm the architecture of your
machine?

thanks
raju

First, the code compiles fine on i386 with 4.4.0 20090113.
Second, I support Joost's position in that the ICE you
posted and the subsequent failure of loading f951 in dbx
suggests the problem is in your installation.  Please,
update to a newer version and try again.

For those reading the archives, this problem is specific to Solaris 8. The
backtrace from this ICE (http://gcc.gnu.org/ml/fortran/2009-01/msg00321.html)
is similar to another problem I encountered with a C program as well. The bug
was reported and fixed as in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38981.

So, can we close this PR as fixed?

I thought it was marked as fixed long time back (2009-01-15) by Joost. Anyway,
the answer is yes.
