Constant Static Objects, not getting initialized in g++

[vnair]

Hi,
I have a static constant object and have initialized in the corresponding cpp file. This goes in a shared library.
the declaration and definition of the variable is as below..

------header file -------------
class LCMAspect {

protected:
int e;
std::string name;

enum {
unknown_e,
none_e,
all_e,
any_e,
last_e
} ;

static const LCMAspect unknown;
....
}

---------cpp file ------------------
const LCMAspect LCMAspect::unknown(LCMAspect::unknown_e, "unknown");

Now from another class in the same module, I am using something like

LCMDelayModeAspect::LCMDelayModeAspect ( ): LCMAspect(LCMAspect::unknown) {}

Now when my application tries to load this library during run time, it gives segmentation fault, where I am trying to access the std::string name field of the static object LCMAspect::unknown.

The same code work fine with the arm compiler.

On tracking the segmentation fault using GDB, I am getting something like this....


(gdb) bt

#10 0xb7f76373 in ?? () from /lib/ld-linux.so.2

the problem i felt is that the static object constructor is not called,

ny one to help me out.. i m really messed up..

I am using g++4.1.2 and GCC version 4.1.2 with Ubuntu..

thanks in advance..
