[Bug c++/19958] New: Global object destroyed that is not constructed

[sabre at nondot dot org]

Consider this testcase:

---
#include <stdlib.h>
#include <stdio.h>

struct A { 
  A() { printf("a\n"); exit(1); }
  ~A() { printf("~a\n"); }
} a;

struct B { 
  B() { printf("b\n"); }
  ~B() { printf("~b\n"); }
} b;
int main() {}
---

G++ 3.4.0, 3.4.2, and 2.96 print:
a
~b
~a

... which destroys B without constructing it.


G++ 3.3.2 prints:
a

... which seems correct (A has not finished construction).

You know your 3.3.x is compiled with --enable-__cxa_atexit.

This is a dup of bug 2474 which is very known bug which only can be fixed via using --enable-
__cxa_atexit on supported targets.

*** This bug has been marked as a duplicate of 2474 ***

I don't really think this is the same as 2474: that is an issue of ctor
ordering, this is one of *destroying objects that weren't created*.
