--- Comment #6 from sje at cup dot hp dot com 2010-02-17 18:03 --- I tried the test with GCC 4.4.0 and 4.3.3 on IA64, in those cases the test failed because we didn't actually pack anything and then the if test failed and we called abort. $ /opt/hp-gcc-4.3.3/bin/g++ -Wpacked packed1.C -o x;./x packed1.C:7: warning: packed attribute causes inefficient alignment for 'INNER' packed1.C:13: warning: ignoring packed attribute because of unpacked non-POD field 'INNER OUTER::inner' Abort(coredump) With the latest compiler on IA64, we try to pack the structure. This results in no warning messages but we then generate a Bus error, probably due to illegal alignment. So the test never worked but this still seems like a regression in behaviour. The HP compiler seems to handle this, it compiles and runs without calling abort. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42837

--- Comment #5 from mmitchel at gcc dot gnu dot org 2010-02-17 17:27 --- Do we have any evidence that this is actually a regression? If this test has never worked on IA64/HPPA, then this is not a regression. It should then be XFAIL'd on those platforms, with this PR left open. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42837

--- Comment #4 from sje at cup dot hp dot com 2010-02-16 18:50 --- Forgot to mention that the test was added along with a fix for PR c++/41788. I don't think the fix or the test are bad though. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42837

--- Comment #3 from sje at cup dot hp dot com 2010-02-16 18:48 --- I would guess this failure started with r156088 when the test was added. I think the test is OK but that ia64 can't handle packing OUTER when one of the fields in OUTER is a struct with a virtual function. -- sje at cup dot hp dot com changed: What|Removed |Added CC||sje at cup dot hp dot com Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|-00-00 00:00:00 |2010-02-16 18:48:29 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42837
