I'm trying to use the Boost.Interprocess library, mutexes, scoped_lock, 
sharable_lock etc...

If I use a simple test program that uses mutex like this, I have no problem:

void test1()
{
    printf("test1 - timed_lock \n");
    printf("trying to get exlusive lock within a timeout of 5 seconds\n");

    boost::interprocess::named_mutex 
mutex(boost::interprocess::open_or_create, "MyExlusiveTimedMutex");
    boost::posix_time::ptime abs_time = 
boost::posix_time::second_clock::universal_time() +
        boost::posix_time::seconds(5);
    if( mutex.timed_lock(abs_time) )
    {
        printf("mutex acquired! do some processing...\n");
        //...do some processing...
        printf("unlocking mutex, quit.\n");
        mutex.unlock();
    }
    else
    {
        printf("mutex not acquired, quit.\n");
    }
    printf("end of test1\n");
}

This test is ok, it builds with no problem.

Then I try to use the scoped_lock functionalities:

void test2()
{
    //open or create the named mutex
    printf("creating mutex...\n");
    boost::interprocess::named_mutex 
n_mutex(boost::interprocess::open_or_create, "ipc_pri_queue_mutex");
    {
        printf("acquiring mutex scoped_lock...\n");
        boost::interprocess::scoped_lock<boost::interprocess::named_mutex> 
sc_lock(n_mutex);
        printf("mutex scoped_lock acquired...\n");

        //wait some time to simulate execution
        printf("execute program...\n");
        sleep(10);
        printf("program excuted...\n");
    }
    printf("out of scope, sharable_lock released\n");
}

Also this test is ok, it builds with no problem.

Finally, I try to use the sharable_lock and I get the error:

void test3()
{
    //open or create the named upgradable mutex
    printf("creating mutex...\n");
    boost::interprocess::named_upgradable_mutex 
n_u_mutex(boost::interprocess::open_or_create, 
"ipc_pri_queue_upgradable_mutex");
    {
        printf("acquiring mutex sharable_lock...\n");
        boost::interprocess::sharable_lock<boost::interprocess::named_upgradable_mutex> 
sh_lock(n_u_mutex);
        printf("mutex sharable_lock acquired...\n");

        //wait some time to simulate execution
        printf("execute program...\n");
        sleep(10);
        printf("program excuted...\n");
    }
    printf("out of scope, sharable_lock released\n");
}

If I build this with -O2 optimization flag, I get this error:

g++ -O2 -I /usr/local/boost_1_49_0 -c main.cpp -o main.o

If I build this without the -O2 flag, the build is ok. Why this? Please 
help.

I did this test on:
OS:  Solaris 10 5/09 s10s_u7wos_08 SPARC
Compiler: sparc-sun-solaris2.10-g++ (GCC) 4.2.1 (20090222) (gccfss)
