[uClinux-dev] Does ucfront work with libstdc++.a?

[kitefree]

Hi,
Recently I have been working on c++ program with uClinux-dist. And I found
there seems to be some problem with using ucfront-g++ with libstdc++.a(gcc 3.4.4). 
As you can see how I build my C++ program,
/home/nerokuo/uClinux/tools/ucfront-g++ arm-linux-g++ -D__PIC__ -fpic -msingle-pic-base -msoft-float -Wall -c main.cpp
/home/nerokuo/uClinux/tools/ucfront-g++ arm-linux-g++ -L/home/nerokuo/uClinux/uClibc/lib -Wl,-elf2flt -Wl,--fatal-warnings -o helloworld main.o -msoft-float -lstdc++

After builing my program successfully. I run it on my verify board and it crashes
with this error when running at this line "test *p = new test(10);",
/mnt> ./helloworld
BINFMT_FLAT: Loading file: ./helloworld

Process helloworld (pid: 18, stack limit = 0x001b6250)

And this is the main.cpp of my test program,
#include <stdio.h>
#include <unistd.h>

class test
{
public:
    test(int n) {i=n;}
    int i;

};

int main(int argc, char *argv[])
{
    test *p = new test(10);
    printf("Nero: test = %d\n", p->i);
    delete p;
    return 0;
}

Could you help identify why this crash happens? Thanks a lot.
