             Bug #: 51330
           Summary: Compiling issue that seems specific to i586 with gcc
                    4.6
    Classification: Unclassified
           Product: gcc
           Version: 4.6.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: remy.garrigue@gmail.com


I'm currently in charge of packaging some sources code, and I've an issue that
SEEMS to be related to gcc 4.6. Not sure thou, I'm not an expert either in the
code nor c/c++

You can find the packaging here:
https://build.opensuse.org/package/show?package=xtreemfs-1.2.3&project=home%3Axtreemfs

As you can see there, packaging for latest opensuse (12.1, factory,
tumbleweed), ubuntu 11.10 and fedora (15, 16) fails under i586 arch. Clic on
the red "failed" or the green "succeeded", then "download log file" and you'll
have the full log, with environment (and gcc) installation plus compilation. 

My point is, with gcc 4.5 older distro packaging is doing fine. With gcc 4.6,
latest one fails on i586. It may be something else, but this is as far as I can
diagnose.

I'm available to give a hand to set up an environment to reproduce my issue and
will be glad of any further information to solve my issue.

Regards,
Rémy

>share/google-breakpad/src/client/linux/handler/linux_thread.cc:251:3: error: expected primary-expression before 'struct'

Can you attach the preprocessed source?  

#define GET_DR(name, num)\
  name->dr##num = ptrace(PTRACE_PEEKUSER, pid,\
                         offsetof(struct user, u_debugreg[num]), NULL)
  GET_DR(regs, 0);


Where is struct user supposed to be defined?  This looks rather like a header
not being included correctly and not really GCC issue.

Package source are available in the "source" panel here:
https://build.opensuse.org/package/files?package=xtreemfs-1.2.3&project=home%3Axtreemfs

The most accurate way to reproduce the build would be to install osc (opensuse
build service command line tools) and type the following
osc co home:xtreemfs xtreemfs-1.2.3  
cd home:xtreemfs/xtreemfs-1.2.3 
osc build openSUSE_12.1 i586 xtreemfs.spec

I spent a couple of hour again trying to fix that issue, adding #include
<sys/user.h> for example, nothing so far. I've no idea where struct user is
defined, but if x86_64 build work with the same source, why i586 wouldn't...
I'm at a lost here

GCC devs do not want to install new packages and download new files for every
bug report, please attach preprocessed source for the failing file.

I tried but I'm unable to produce the preprocessed files. So... well, I'll try
to package my stuff using gcc 4.5 later. Regarding 4.6, I can't afford to spend
more time on looking into the matter, so I guess we'll never know.

Sorry for the trouble.

Thus, invalid.
