--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
I'll note that
f951: Fatal Error: Maximum supported identifier length is 63
which is a hard compiled-in limit that is used throughout the frontend for
static allocation of names.
gfortran.h:#define GFC_MAX_SYMBOL_LEN 63 /* Must be at least 63 for F2003.
*/
so it seems we use the minimum allowed implementation-defined limit
(which is also the default, unless -std=f95).
