dbx/cc troubles

I compile the following code with cc -g -xdebugformat=dwarf

static double foo(double bar)
{
bar++;
return bar;
}
int main()
{
foo(0.0);
return 0;
}

When I load the binary into dbx, set a breakpoint at the line
containing "return bar;" and print bar; dbx gives me "bar = 0.0"

If I compile with CC, I get "bar = 1.0".

The dwarf debug info generated by CC sets the DW_AT_location for bar
to the correct stack frame offset. This is not the case for cc.

I am using sun studio 12. Both compilers are version 5.9.

Is there a cc command line option to correct the dwarf debug info?

Thanks,
James
