------- Comment #1 from debian-gcc at lists dot debian dot org 2006-04-09 10:10 -------
Seems to occur quite frequently, here's another test case:
struct GdkColor {
unsigned long pixel;
unsigned short red;
};
struct GtkStyle {
struct GdkColor bg;
};
struct GtkStyle *gtk_style_new (void);
void pthreada_create(unsigned long *);
void start_synaescope(void) {
unsigned long synaescope_thread;
struct GtkStyle *style = gtk_style_new();
struct GdkColor *color = &style->bg;
color->red = 0;
pthreada_create(&synaescope_thread);
}

Can you file that into a different bug?
As it is a different issue.
Actually the orginal testcase here was not fixed by the patch which is going to
fix PR 26626 either.
So reopening.

Daniel, since you fixed 26626, do you think you could take a look at this one
too?
