* 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)
