    UPS developers,

I'd like to be able to debug the following example

>>>>>>
localhost:/home/balay/junk>cat x.c

typedef struct _p_Vec*         Vec;
int main(void)
{
  Vec v;
  VecCreate(&v);
  v = 0;
}


localhost:/home/balay/junk>cat y.c

typedef struct _p_Vec*         Vec;
struct _p_Vec {
  int a[10];
  char *type;
}

VecCreate(Vec *v)
{
  *v= (Vec)malloc(sizeof(struct _p_Vec ));
}
localhost:/home/balay/junk>gcc -g x.c y.c
localhost:/home/balay/junk>ups a.out

>>>>

place a breakpoint at x.c:7 < code: v = 0 >
I'd like to be able to click on v - and the debugger - resolves
the type properly (from the info in y.c or something)

Currently 'Expand' on 'v' gives 'v is not a structure or union'

But gdb does resolve this structure properly

(gdb) p *v
$1 = {a = {-1073742899, 0, -1073742876, -1073742855, -1073742820, -1073742807, 
    -1073742790, -1073742759, -1073742719, -1073742702}, 
  type = 0xbffffcae "LESSOPEN=|/usr/bin/lesspipe.sh %s"}

We use this design extensively - and because of it - I'm stuck to using
gdb for debugging. I'd appreciate if this can be added to ups.

Thanks,
Satish
