Script of the compile/link

I compiled and linked on Ubuntu x86_64 for the Raspberry Pi.
The compiler/linker completed with no errors.

int main() { return 0;}

When hello is executed on Raspberry Pi, I got a Segmentation fault.

If I compile on Ubuntu with -nostdlib and explicitly list the Raspberry Pi
crtxxx.o files and the Raspberry Pi libs, the resultant executable completes
without error on Raspberry Pi.

I attached a script of the compile actions on Ubuntu.

I believe this to be a problem with the crtxxxx.o files and the libs
distributed with arm-linux-gnueabihf-gcc-4.6 package.

The same package on Raspberry Pi works Ok.
