Hi,
The problem appears in revision 201034 in version 4.9. I attached a
one-line patch that fixes it. I also reported this problem
at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57803
I bootstrapped and ran the regression tests for this patch on x86_64-linux
and all tests pass.
In method "gfc_build_dummy_array_decl()" in gcc/fortran/trans-decl.c,
the loop on line 978 should break immediately after "packed" is set to
"PACKED_PARTIAL". All the iterations after "packed" set to
"PACKED_PARTIAL" do not perform any useful work, at best they just set
"packed" again to "PACKED_PARTIAL".
Thanks. I've installed the patches from all of your emails which
address these issues.
I'm a bit curious, are you finding these by inspection of the sources or
via some kind of analysis code?
Thanks again,
Jeff
