Re: While compiling binutils-2.17, i get the error "dereferencing type-punned pointer will break strict-aliasing rules"


Hi Mayank,

(struct bfd_link_hash_entry **) &h))) -->The error points to this line in all places.

The problem is that variable h is of type struct coff_link_hash_entry *, whereas the function pointer expects a variable of type struct bfd_link_hash_entry *.

Does anybody know how to fix the above error.

This is not an error. The coff_link_hash_entry structure includes a bfd_link_hash_entry structure as its first field. (See bfd/libcoff.h). Hence it is OK to cast the pointer in this way.


There may be more elegant ways to handle this sort of thing, but the code does work.

Cheers
  Nick
