Confirmed. The problem is that we do in module.c's gfc_use_modules:
gfc_use_module (module_list);
if (module_list->intrinsic)
free_rename (module_list->rename);
But then in trans-decl.c's gfc_trans_use_stmts:
for (rent = use_stmt->rename; rent; rent = rent->next)
While freeing the memory is probably fine for build-in intrinsic modules like
ISO_Fortran_env and ISO_C_Binding; however, doing so for intrinsic modules
which are loaded for a file is wrong. (Side note: We should free the rename
list in trans-decl.c to avoid mem leaks.)
