FIXED on the trunk (4.6). Thanks for the bugreport.
(The fix is to print an error if the constructor is too large; the error
message points to -fmax-array-constructor= which can be used to modify the
limit.)

Regardless, we should catch this and issue the error message about
-fmax-array-constructor. I don't see why we would want to do anything else.

Workaround: Use a sufficiently large -fmax-array-constructor=, e.g.
-fmax-arra

Even shorter:
module proc8
implicit none
integer, parameter :: N = 256
logical, dimension(N**2), parameter :: A = .false.
logical, dimension(N,N), parameter :: B = reshape ( (/ A /), (/ N, N /) )
end module

Here is a reduced test case:
module proc8
implicit none
private
integer, parameter :: n_cflow

I isolated the bug further and prepared a roughly 1 MB sniplet which triggers
the ICE. It seems that the definition of the more than 500 logical array and
packing them in one big array constructor is not w

Regarding the version: Try gfortran -v -- that does not only show the version
but also the data and (possibly) the SVN reversion.
Regarding the test case: I think it would be helpful, if you could reduce it a
bit.
--- Comment #2 from janus at gcc dot gnu dot org 2010-07-01 11:32 ---
Also, please be more specific about which gfortran version you're using. Your
error message seems to suggest something 4.5-ish. Is this the 4.5.0 release
version? And is it possible for you to try 4.4.x or 4.6 trunk?

Please put it down for download somewhere (it's indeed too large to attach).
