--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
So running:
$ g++ pr77745.C -O2 -flto -fno-use-linker-plugin -m32 -fpic -mtune=native
for:
$ cat pr77745.C
// { dg-do run }
//
#include <new>
#include <stdio.h>
//inline void* operator new(__SIZE_TYPE__, void* __p) noexcept { return __p; }
long
__attribute__((noinline))
foo(char *c1, char *c2)
{
long *p1 = new (c1) long;
*p1 = 100;
long long *p2 = new (c2) long long;
*p2 = 200;
long *p3 = new (c2) long;
*p3 = 200;
return *p1;
}
int main()
{
union {
char c;
long l;
long long ll;
} c;
if (foo(&c.c, &c.c) != 200)
{
fprintf (stderr, "aborting\n");
__builtin_abort();
}
}
Aborts for all GCC releases I have (4.5.0+).
