[Bug ada/34173] New: [4.3 regression] FAIL: gnat.dg/release_unc_maxalign.adb execution test

[andreasmeier80 at gmx dot de]

gnat.dg/release_unc_maxalign.adb execution test fails for me since 20.11.2007.
At 19.11.2007 it whas worked.

Compiler version: 4.3.0 20071120 (experimental) (GCC) 
Platform: i686-pc-linux-gnu
configure flags:
--enable-languages=ada,c,c++,fortran,java,objc,obj-c++,treelang
--with-mpfr=/usr/local

It fails with r130312 and works with r130286

 Thanks for opening the PR. We have identified what is causing this
 and are qualifying a candidate fix. This is an old bug actually, showing
 up on this recently added testcase exercising the fix for another issue.

 Cheers,

 Olivier

I guess you need to ask Daniel what's going on exactly here.

Have you tried your @gcc.gnu.org account?

 Humm, no. I tried the login/password combination sent to me more
 than two years ago :)

 I'm obviously not very used to doing these operations and will give
 my @gcc.gnu.org a try. Thanks.

        * decl.c (gnat_to_gnu_entity) <case E_Array_Type>: When setting
        the alignment on the GCC XUA array type, set TYPE_USER_ALIGN if
        this is from an alignment clause on the GNAT entity.
        * utils.c (create_field_decl): Rewrite the computation of DECL_ALIGN
        to distinguish the case where we set it from the type's alignment.
        When so, propagate TYPE_USER_ALIGN into DECL_USER_ALIGN to indicate
        whether this alignment was set from an explicit alignment clause.
