Debugging modules

Question

Hello,
is debugging of modules supported in current version of dbx and f95 for linux?
Sample program:
modul.f90:
MODULE modul
integer,parameter:: KND=KIND(1.)
CONTAINS
real(KND) function F(x)
real(KND) X
F=SIN(X)+COS(X)
end function
END MODULE modul
main.f90:
program MAIN
use modul
real(KND) Y
Y=1.
Y=F(Y)
write (*,*) Y
end program
compilation:
lada@spiranthes:~/f/test> f90 -g modul.f90 main.f90 -o Sun-i386-Linux/test
modul.f90:
main.f90:
Linking:
dbx output:
(dbx) cd /home/lada/f/test/Sun-i386-Linux
(dbx) debug /home/lada/f/test/Sun-i386-Linux/test

execution completed, exit code is 0
(dbx)
I simply can't get into the module function. I'm using the latest build for linux on Suse Linux 10.0.

We are in the process of converting the fortran debug information
from stabs to dwarf, which is required for Linux support. But
the conversion is not quite complete yet. The next version of
Sun Studio Express (in a month or two) should have much better
module support in dbx.
