That is less comfortable for them than GDB.

As otherwise users use iFort which has various DWARF incompatibilities needing
to be thus supported by gdb, iFort does not support build-id and other GNU
features so it is difficult to workaround all the iFort issues with the GNU
toolchain around.

You are right GDB should also support it.  That is not targeted by this Bug.

(gdb) p q.a
A syntax error in expression, near `.a'.
(gdb) p q%a
$3 = 3


> Do you want to support ifort syntax or not?

'.' is not an iFort syntax, it is some legacy Fortran syntax.
Yes, I would like gfortran to support the '.' syntax.
