Hi!

I don't seem to get gfortran to warn when assigning to an unallocated array
(I've tried '-g -fbounds-check -Wall -pedantic', which I take it should cover
it all), it only segfaults at run-time...

While this is obviously menial stuff, the Lahey compiler for one nicely warns
both at compile- and run-time.

Just for the record...

Thanks!

Philippe

PS: a reduced example:
!
PROGRAM Test
!
INTEGER, ALLOCATABLE :: Array(:)
!
Array = 256
!
END PROGRAM Test
!

PPS: I've tried with
GNU Fortran (GCC) 4.3.0 20071119 (experimental) [trunk revision 130286]
