--- Comment #2 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
F95 bug. Still present. In the generated code, the size of Y is computed before
the bounds for the F result are set, which leads to the error.
Slightly reduced testcase:
$ cat a.f90
program bug3
real y(2)
y = f(2)
print *, y
contains
function f(x)
integer x
real f(x)
integer y(size(f))
write(*,*) 'size(f) = ',size(f)
write(*,*) 'size(y) = ',size(y)
f = -42
end function f
end program bug3
$ gfortran a.f90 -std=f95 && ./a.out
size(f) = 2
size(y) = 0
-42.0000000 -42.0000000
Slight modification of the source leads to an ICE on what I think is invalid
code:
$ cat a.f90
function f(x)
integer x
integer y(size(f))
real f(x)
write(*,*) 'size(f) = ',size(f)
write(*,*) 'size(y) = ',size(y)
f = -42
end function f
$ gfortran a.f90 -std=f95 && ./a.out
a.f90:3:0:
integer y(size(f))
1
internal compiler error: in gfc_conv_expr_descriptor, at
