GCC doesn't merge the two strings in this program:

char *a = "This is a string";
char *b = "string";

        .file   "bug-88959.c"
.globl a
        .section        .rodata
.LC0:
        .string "This is a string"
        .data
        .align 4
        .type   a,@object
        .size   a,4
a:
        .long   .LC0
.globl b
        .section        .rodata
.LC1:
        .string "string"
        .data
        .align 4
        .type   b,@object
        .size   b,4
b:
        .long   .LC1
        .ident  "GCC: (GNU) 3.1 20010701 (experimental)"
