            Bug ID: 64368
           Summary: [5 Regression] Several libstdc++ test failures on
                    darwin after r218964.
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal

cris-elf too, observed starting in r218951:218978 here, so I suggest not
hand-waving away our reports, in particular as they indicate pointer-dependent
bugs.  I haven't investigated each commit, but looking at the "svn diff
-r218951:218978" a wild guess would be a bug in the rewrite-changes perhaps
related to_GLIBCXX_USE_WCHAR_T.

If you can't see it on your system, please run the test under valgrind.

The .log entries indicate bugs consistent with the previously quoted log
entries (i.e. some allocation bug):

PASS: 22_locale/locale/cons/6.cc (test for excess errors)
core: 4 byte misaligned read to address 0xa2ce236 at 0x45788

BTW, the ext/profile/mutex_extensions_neg.cc errors were deliberately fixed in
r218988:218990.

Also fails on i386-unknown-freebsd10.1:

Who is waving anything away? I've been fixing things for Darwin at all hours of
the day, while on vacation and while ill, so don't appreciate that comment.

I have run the years in valgrind and saw no problem on Linux.

Someone could always try debugging things themselves, even if just posting full
stack traces to this report.

I wasn't referring to you.  Apparently I was referring to a comment that was
supposed to be ignored.

Sorry!
Your work and diligence is much appreciated.
Get well soon.

Created attachment 34344
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=34344&action=edit
Call-trace for testsuite/22_locale/locale/cons/6.cc on cris-elf, a "newlib
target"

Plain execution trace from 22_locale/locale/cons/6.cc compiled with default
testsuite options, so inlining and whatever effects apply.

In the trace, lines with ">" denotes function calls, "<" are returns, with
indentation supposed to show the call-level.  The first four columns are the
hexadecimal values of the first four parameters as applicable (actually,
"parameter registers" but none are larger than 32 bits here, so same thing) /
ditto return values, padded with random contents.  (The fifth column is
cumulative execution times at each call-level.)

By a quick glance it seems the freed-but-not-allocated pointer, 0x5e23a, is
also the argument to the last call to strlen.

HTH.

smaller)

Note that the last failures belong to another PR: they come from a later commit
and I see several of them on darwin (see FX tests). I have no inclination to
open a PR for them as long as the PRs I open are rotting for ever.

This PR is a month old today, hardly forever. I'm going to fix it.

Confirmed, thanks for the fix. The first failure is covered by pr64797, the
23_containers/* failures are covered by pr64813, and I'll open a new PR for the
remaining ones ASAP. I am waiting for feedback from the other platforms before
closing the PR as FIXED.

Great, thanks for confirming it. As you say, let's leave this open for now in
case HP or Rainer still sees some of these failures.

JFTR, for cris-elf at r220153, my autotester is now down to the following
regressions since the start of the epoch (11 years ago):

gcc.sum gcc.dg/tls/alias-1.c
libstdc++.sum 28_regex/traits/char/isctype.cc
libstdc++.sum 28_regex/traits/wchar_t/isctype.cc

(all covered by other PR:s, the last two may be on your short list :-)
Thanks!

Just for the record: all the failures on Solaris (with the exception of
PR libstdc++/64797, of course) are gone, too.

Thanks.
