I have applied the gcc PR32219 patches which use not_null_ptr() when testing existence of _stdio_init, _locale_init, __errno_location, and __h_errno_location. This gets me past __uClibc_init but now I die in _atexit.c: exit() routine which calls _stdio_term. I have put the same not_null_ptr() functionality in and the problem goes away but I did not see any changes in the current upstream to deal with this same issue.

My test program is foo.c compiled and linked as shown below:

int main(int argc, char **argv)
{
    return 0;
}

gcc -static -o foo foo.c
