--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
This applies to all diagnostics, not just -Wconversion:
class X {
X() : bad(1),
good(1)
{ }
void* bad;
int good;
};
i.cc: In constructor ‘X::X()’:
i.cc:3:11: error: invalid conversion from ‘int’ to ‘void*’ [-fpermissive]
good(1)
^
As Manu said, it's unlikely that the member name can be printed easily, because
the code that checks the initialization works with types, and the name of the
variable isn't known at that point. There are also dozens of different errors
and warnings that can happen there (not just -Wconversion) so they would all
need to be updated.
If the location was correct and shown with a range marking the variable that
would remove the need for printing the name:
i.cc: In constructor ‘X::X()’:
i.cc:2:11: error: invalid conversion from ‘int’ to ‘void*’ [-fpermissive]
X() : bad(1),
^~~~~~
I'm changing the priority from enhancement to normal, because printing the
wrong location is a bug.
