gcov in conjunction with arm-elf-gcc

Hi all,

we're still having trouble with coverage analysis when using arm-elf-gcc.

We fixed the problem with the ctor functions. Than we tried to analyse a 
simple program. In a first try we used gcc and all worked fine.
Then we recomplied the program, using arm-elf-gcc. But this time we had 
little success.

Has somebody an idea what the problem could be?


Thanks a lot & Grüße

int main(int argc, char *argv[])
{
        if( argc == 1 )
        {
                printf("no options used!\n");
        }
        return 0;
