             Bug #: 53602
           Summary: Libre Office causes an internal compiler error
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: andy@benton.eu.com


Libre Office 3.5.3 compiles fine for me with Gcc 4.7 on x86_64 but on
i686 the build dies with this error:

Making:    all_uno-skeletonmaker.dpobj

See <http://gcc.gnu.org/bugs.html> for instructions.

The "internal compiler error" and the request for a bug report to be
sent to gcc makes it look like a bug in Gcc 4.7. The actual code that
causes the problem looks like this:

void checkDefaultInterfaces(
         boost::unordered_set< OString, OStringHash >& interfaces,
         const boost::unordered_set< OString, OStringHash >& services,
       const OString & propertyhelper)
{
    if ( services.empty() ) {
        if (interfaces.find("com.sun.star.lang.XServiceInfo") !=
interfaces.end())
            interfaces.erase("com.sun.star.lang.XServiceInfo");
    } else {
        if (interfaces.find("com.sun.star.lang.XServiceInfo") ==
interfaces.end())
            interfaces.insert("com.sun.star.lang.XServiceInfo");
    }

    if ( propertyhelper.equals("_") ) {
        if (interfaces.find("com.sun.star.beans.XPropertySet")
            != interfaces.end())
            interfaces.erase("com.sun.star.beans.XPropertySet");
        if (interfaces.find("com.sun.star.beans.XFastPropertySet")
            != interfaces.end())
            interfaces.erase("com.sun.star.beans.XFastPropertySet");
        if (interfaces.find("com.sun.star.beans.XPropertyAccess")
            != interfaces.end())
            interfaces.erase("com.sun.star.beans.XPropertyAccess");
    }
}

Googling on the error found this bug report at Ubunut:
https://bugs.launchpad.net/ubuntu/+source/gcc-4.7/+bug/1007616
But sadly they have no solution.

I have previously built Libre Office 3.5.3 on i686 with Gcc 4.7, what was
different this time was that I used an svn pull of the Gcc 4.7 branch
(r188021). Ie, Gcc had changes that had been checked into the Gcc 4.7 branch
since gcc-4.7.0 was released.

Looking at http://gcc.gnu.org/bugs/#detailed it seems that I'm supposed to
provide the output of something like:

gcc -v -save-temps all-your-options source-file

Sadly I have no clue how gcc was called by the Libre Office dmake system (I am
completely unfamiliar with dmake). If someone could guide me on how to find out
how gcc was called I would appreciate it.

Another problem with debugging this is that I can only reproduce this on a 32
bit system and all my 32 bit computers are old and slow. Compiling Libre office
takes about 20 hours but fortunately the error occurs only about 4 hours into
the build
