When compiling a small file with standard flags the compiler crashes.
This seems to be related to a WHERE construct.
The code is accepted without warnings by e.g. Intel fortran compiler and
others.
The version of gfortran is 4.2.0 20060819

Oskar,
This works for me with gcc-4.2.0 20060905; I know of nothing that would have
effected this change so I am at a bit of a loss. I hung a main program on it
and checked the output too.
Paul

Paul, the code fails with
troutmask:kargl[205] gfc --version
GNU Fortran 95 (GCC) 4.2.0 20060711 (experimental)
Copyright (C) 2006 Free Software Foundation, Inc.
but works with
troutmask:sgk[248] gfc4x --version
GNU Fortran 95 (GCC) 4.2.0 20060906 (experimental)
Copyright (C) 2006 Free Software Foundation, Inc.
On a quick scan of ChangeLog, I did not see an entry that jumps out that
fixed/caused the problem.
Oskar,
Can you update to a newer version and verify the code works?

Oskar,
We believe that this bug is "fixed"; however, I will take you tst.f90 and put
it in the gfortran testsuite, since we do not know what moved to produce both
the regression and the "fix".
As I said to the list, we will be very grateful if you would submit any
problems that you might have in the future.
Paul Thomas

Subject: Re: ICE: Segmentation fault on valid code
Yes that's fine with me.
I don't have access to the computer where I originally noticed the
problem until the end of the week so I haven't been able to try any
later snapshot version. I have compiled the latest trunk on a different
machine (i686) and have verified that the testcase compiles without
crash there. So it appears to be fixed.
Thanks for the response!
