Or -std=f95; data.c has:
/* Overwriting an existing initializer is non-standard but usually only
provokes a warning from other compilers. */
[...]
gfc_notify_std (GFC_STD_GNU, "Extension: re-initialization "
"of '%s' at %L", symbol->name, &expr->where);
-pedantic gives a warning, -std=f* an error.

Since 9 values are consecutively overwritten - however, this can be fixed.

Since only one value is overwritten, e(2) - e(1) and e(3) are initialized only
once.
