I guess it depends upon what you mean by a data section. If you mean a section
with the PROGBITS type and the ALLOC and WRITE flags, then I would agree. But
to be clear such a section will not have the EXECUTE flag. (I am restricting
myself to ELF here, but similar concepts exist for other file formats).

Are you sure about this ? If the code is in a non-executable section then it
should be linked into a non-executable segment, and so it should never be run.
Do you have an example to demonstrate the behaviour you describe ?

Well I am not convinced enough of the utility of this warning to want to
implement it myself, but if someone volunteers I am not going to object...
Cheers
