2 * The conversation with Matti Rintala on STLport forum 2005-08-24:
3 *
4 * Do you mean ISO/IEC 14882 3.6.3 [basic.start.term]?
5 *
6 * Yes. "Destructors (12.4) for initialized objects of static storage duration
7 * (declared at block scope or at namespace scope) are called as a result
8 * of returning from main and as a result of calling exit (18.3). These objects
9 * are destroyed in the reverse order of the completion of their constructor
10 * or of the completion of their dynamic initialization."
11 *
12 * I found a confirmation on the web that gcc may not strictly conform
13 * to this behaviour in certains cases unless -fuse-cxa-atexit is used.
14 *
15 * Test below give (without -fuse-cxa-atexit)
16
17Init::Init()
18Init::use_it
19It ctor done <-- 0
20Init::use_it done
21Init ctor done <-- 1
22Init2 ctor done <-- 2
23It dtor done <-- 0
24Init2 dtor done <-- 2
25Init dtor done <-- 1

28 * but should:

30Init::Init()
31Init::use_it
32It ctor done <-- 0
33Init::use_it done
34Init ctor done <-- 1
35Init2 ctor done <-- 2
36Init2 dtor done <-- 2
37Init dtor done <-- 1
