Please follow the bug reporting instructions
http://gcc.gnu.org/bugs/
when reporting bugs. They tell you to use -Wall, which would have shown
that your code has undefined behavior:
t.c:11:9: warning: format '%llx' expects type 'long long unsigned int', but
argument 2 has type 'long long unsigned int:40'
C bit-fields in GCC follow DR#120 and some other DRs, whereby
'long long unsigned int:40' is an integer type, is not promoted because
it is wider than int, and can have arithmetic carried out on it which is
40-bit modulo arithmetic.
