gcc-4.1.0-0.20051206r108118 emits wrong .size directives for
statically initialized objects with a flexible array member,
e.g.:
struct {int x; int y[];} obj = {1, {2, 3}};
.globl obj
.data
.align 4
.type obj, @object
.size obj, 4
obj:
.long 1
.long 2
.long 3
Can this have serious effects (like overlapped or split objects),
or is .size used only for e.g. debugging?
I observe very strange effects when a particular complex program
is changed from explicitly sized arrays to flexible array members:
variables change values spontaneously, inserting printfs affects
places where they change values. I wonder whether this can be the
cause (the assembler output differs in more places than mere .size
directives because of changed types).
