             Bug #: 52778
           Summary: gcc crashes with -flto on PA-RISC
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: mikulas@artax.karlin.mff.cuni.cz
              Host: hppa-linux-gnu
            Target: hppa-linux-gnu
             Build: hppa-linux-gnu


When compiling a specific version of the Links browser on PA-RISC with -flto, I
got a crash in lto1.

The crash happens on gcc-4.7.0 and gcc-4.7.0-RC-20120302. It doesn't happen
with gcc-4.6.[23].

I compiled gcc without optimization to rule out a possibility of miscompiled
compiler. The crash still happens.

I couldn't reduce the crash to a simple example --- even minor changes in the
source code resulted in the crash going away. So I'm uploading all the source
files and include files so that someone can reproduce the crash. The system is
Debian 5 on PA-RISC.
