s5 ();
++kh;
}
}

p7 (int q3)
{
yv (q3);
rp (0, 0, 0, 0, 0, 0, 0);
return 0;
}

Inconsistent CFI state!

'naked'
This attribute allows the compiler to construct the requisite
function declaration, while allowing the body of the function to be
assembly code. The specified function will not have
prologue/epilogue sequences generated by the compiler. Only basic
'asm' statements can safely be included in naked functions (*note
Basic Asm::). While using extended 'asm' or a mixture of basic
'asm' and C code may appear to work, they cannot be depended upon
to work reliably and are not supported.
