I am assuming I am doing something wrong but I am hoping someone can give me a clue as to where to look.
I'm trying to write an AIX device driver using g++. The drivers do not have a __start or main, so I have to call the global constructors and destructors myself. I've written code attempting to make sure they get constructed before any globals are accessed and no global access happens after they are destroyed. But my trace shows that the object that is suppose to do that is getting its destructor called recursively. The essence is that I have an automatic variable. The constructor calls the global constructors; the destructor calls the global destructors. Line 1 and 10 you see this variable's destructor getting called. The second call returns at line 13. The first call returns at line 23. The second call does nothing because I have already flipped the bit that says that the global destructors need to be called. So the second call comes and goes without much fuss. The only thing unusual about the config_lock class is it has two static members. I could move those and just have global C statics if necessary. The static members are an int and an lock_t (C types). I can write code to cope with this but I assume that this is not suppose to happen. My fear is that I am trashing something and just getting lucky that I am not crashing. I first want to make sure (from comments from this mailing list) that it is not suppose to happen. The second thing I'm hoping for is some suggestions on what may be happening. The first call appears to be destroying objects, then calls itself again, then continues destroying objects, then returns. Why is it calling itself again? Any ideas? 1 **** config_lock_dtor 2 get_lockl_ctor 3 get_lockl_ctor ret 0 from line 108 4 global_dtors 5 global_dtors 004E 0000 0000 0000 6 dtor 7 dtor ret 0 from line 24 8 dvr_simple_lock_dtor 9 dvr_simple_lock_dtor ret 0 from line 31 10 **** config_lock_dtor 11 get_lockl_ctor 12 get_lockl_ctor ret 0 from line 108 13 **** config_lock_dtor ret 0 from line 75 14 get_lockl_dtor 15 get_lockl_dtor ret 0 from line 116 16 free ptr 70BDDFC0 17 free ret 0 from line 32 18 free ptr 70BCF480 19 free ret 0 from line 32 20 free ptr 70BCF820 21 free ret 0 from line 32 22 global_dtors ret 0 from line 82 23 **** config_lock_dtor ret 0 from line 75 Thank you for you help.
