Hi Richard,
: 2000-08-27 Nick Clifton <nickc@redhat.com>
:
: * tree.c (make_node): Initialise DECL_ALIGN and TYPE_ALIGN to
: BITS_PER_UNIT not 1, since alignments are now in bits not
: bytes.
:
: We discussed this once before. These default values really shouldn't be
: used, so one could argue they should be setting it to zero. Why are
: incompletely laid-out types or objects being used?
I have no idea. The test case looks like this:
typedef struct _foo foo;
extern foo bar;
struct _foo { int a; };
void baz (void) { bar.a = 0; }
It is the assignment to 'bar' in baz that is causing the problem to
trigger.
Cheers
Nick
