g77 bug report

This is with egcs - g77:
#uname -a
Linux bacchus.pc1.uni-duesseldorf.de 2.0.33 #1 Wed Feb 25 11:42:35 CET
1998 alpha unknown
# eg77 -v
Reading specs from
/usr/local/share/egcs/lib/gcc-lib/alphaev5-dec-linux-gnu/egcs-2.91.12/specs
gcc version egcs-2.91.12 980302 (gcc-2.8.0 release)
The following program gives a segmentation fault at the second
array access, while the first one does work:
program rotor
implicit none
integer KaKc(0:5,-5:5,0:2)
integer cj
call setkac( KaKc, 5 )
stop
end
c ---------------------------------------------
subroutine setkac( KaKc, Jmax )
implicit none
integer Jmax
integer KaKc( 0:Jmax, -Jmax:Jmax, 0:2 )
integer cj, i
cj = 0
i = -cj
KaKc( cj, i, 1 ) = 0
write(*,*) 'Here we go !'
KaKc( cj, -cj, 1 ) = 0
return
end
It does work on DU 4.0b using the system f77 compiler.
Is this a known problem ? Any workaround ?
I do have all code that is using such constructs all over ?
(And I don't know the code.)
Cheers,
Jochen
