Hi all,
well this is pretty much confusion to me as well, but here is
scenario. I have two shared objects file and one loader executable.
loader calls extern function in shared1 , which has one class ,
initialize it and run its method , which would call extern in shared2=
..
after shared2 extern function returns, the "this" pointer get 0x00 =
in
A::Run(),
any guess what would have been happened, I have using gcc version 4=
+
to build the project.
** loader.cpp
- calls run_test(); in shared1.cpp
** shared1.cpp
class A {
public:
Run() { mum_tum(); doWell(); }
doWell() { }
};
extern void run_test() {
A *a = new A();
a->Run();
}
** shared2.cpp
extern void mum_tum() { }
thank you.
with three different method naming conventions in so short a code, plus=
a question of non-reproducable behavior where even the description of=
what's allegedly wrong is suspect, this is clearly a troll posting

thx for the reply . but, the code i am working with is pretty much big an=
d complex, so I described the scenario with short pseudo code. The main pro=
blem relies when actual this pointer of "class A" get vanished after call t=
o extern function in second shared dll. What I am concerned here is if it i=
s case of stack corruption or something. I have checked similar case from g=
db forum but no clue.
can you get a short, complete program to exhibit the problem?
