testcase:
#include <cassert>
struct foo
{
int mem1;
int foo::* mem2;
};
int main()
{
foo x = {0};
assert(x.mem2 == foo().mem2);
return 0;
}
result:
$ g++42 bug.cpp -o bug; ./bug
assertion "x.mem2 == foo().mem2" failed: file "bug.cpp", line 12
Aborted (core dumped)

------- Comment #1 from rguenth at gcc dot gnu dot org 2007-06-08 10:36 -------
Confirmed.
{
struct foo x = {.mem1=0, .mem2=-1};
<<cleanup_point struct foo x = {.mem1=0, .mem2=-1};>>;
<<cleanup_point <<< Unknown tree: expr_stmt
bar (x.mem2 == (TARGET_EXPR <D.2011, {}>).mem2) >>>
>>;
return <retval> = 0;
}
2.95 used zero for .mem2 initialization.

It's still broken in 4.1, so we want to keep it open (generally we don't close
wrong-code bugs as fixed only in later releases - unless the branch is closed).
