 Hi. I'm using gcc 2.6.3 in a Linux (1.2.3) system. I've come across what
looks to me like a bug. I am not very sure exactly how I should accomplish
(if I even can) this particular sort of initialisation/definition; in fact
my other compilers (various levels of AIX compiler) croak with errors of
one sort or another. But gcc quietly produces bad assembler code, so I
thought you'd likely want to hear about that, at least. If you can tell me
how I should accomplish my intent, that would be great, but don't sweat that.

 For reasons I won't bore you with, I want to make a vector of pointers,
each pointing at an instance of a structure. I want to define this thing
dynamically (ie, I want to initialise it in-place, without specifying its
final size explicitly).

 I've used the following C source to attempt this:

----------------------------------------startC----------------------------
#define MAXtoken 25
static char Rhost[MAXtoken+1]="";
static int *Ruser=0;

static struct token_s {
        char * tname;
        enum ttype_e {
                ttint=1,
                ttstring=2,
        } ttype;
        void *tptr;
};
typedef struct token_s token_t;
typedef token_t *token_p;

static token_p xx[]={ &(token_t) {"foo",ttint, (void *)&Rhost},
                      &(token_t) {"goo",ttint, (void *)&Rhost},
                      &(token_t) {"hoo",ttint, (void *)&Rhost},
                       (token_p) 0};
----------------------------------------endC------------------------------
 This compiles without error, but produces the following assembler code,
which you'll notice incorrectly refs LC6 in each token_t as the text
pointer; this ultimately leads to a failing link.

 (The compile command string was:  gcc -c -S gccbug.c  )

------------------------------------StartS--------------------------------

        .file    "gccbug.c"
gcc2_compiled.:
___gnu_compiled_c:
.data
_Rhost:
        .ascii "?0"
        .space 25
        .align 2
_Ruser:
        .long 0
        .align 2
_xx:
        .long LC1
        .long LC3
        .long LC5
        .long 0
.text
        .align 2
LC5:
        .long LC6
        .long 1
        .long _Rhost
LC4:
        .ascii "hoo?0"
        .align 2
LC3:
        .long LC6
        .long 1
        .long _Rhost
LC2:
        .ascii "goo?0"
        .align 2
LC1:
        .long LC6
        .long 1
        .long _Rhost
LC0:
        .ascii "foo?0"

---------------------------EndS------------------------------------

 As I said, I welcome any comments, although I will most likely just try to
find a simpler way to solve my problem, and likely won't upgrade my gcc
(at least right now); I just wanted to report the bug for your interest.

 Thanks for the software ..../Leigh
