Subject: [Bug c++/40389] optimizer bug (possibly)
Date: Tue, 09 Jun 2009 21:31:00 -0000 [thread overview]
Message-ID: <20090609213113.29039.qmail@sourceware.org> (raw)
In-Reply-To: <bug-40389-17817@http.gcc.gnu.org/bugzilla/>
------- Comment #6 from pinskia at gcc dot gnu dot org 2009-06-09 21:31 -------
I think this code is undefined as there is an address of a local variable being
taken and stored (explicitly when doing:
__attribute__ ((noinline)) H (A *b) : a (b)
{
p = 0;
n = 0;
if (a != 0)
a->k.bar (this);
}
this is an address of a local variable (the temp in baz).
