I think I understand what's happening, although I don't know how to fix it:
(1) gfortran.dg/class_45a.f03 is compiled and generate g_nodes.mod,
(2) gfortran.dg/class_45b.f03 is compiled and run with -O0,
(3) g_nodes.mod is cleaned due to "! { dg-final { cleanup-modules "G_Nodes" }
}"
(4) gfortran.dg/class_45b.f03 is proceeded with -O1 but g_nodes.mod is no
longer there, hence the failure:
Fatal Error: Can't open module file 'g_nodes.mod' for reading at (1): No such
file or directory^M
FAIL: gfortran.dg/class_45b.f03 -O1 (test for excess errors)
Excess errors:
