>Description:
In foo.c:

foo()
{
  int i;
}

in main.c:
main()
{
  foo();
}

compile with:
cc -gstabs -c main.c
cc -gstabs -c foo.c
cc -gstabs main.o foo.o -o main

The final ELF executable (main) has the following n_string for the "int i" instance in foo():

i:(1,1)

and the definition of "int" in both foo.o and main.o is:

int:t(0,1)=r(0,1);-2147483648;2147483647;

Since all typedefs for int are of type 0,1 and the instance is 1,1 there is no way to match the instance up with its type.
