             Bug #: 55736
           Summary: lto ICE: tree code ''junl is not supported in LTO
                    streams
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto

massive amd64 example

Another LTO breakage:
lto1: internal compiler error: tree code ‘�    ’ is not supported in LTO
streams

Too bad, the smallest test case I have right now is 73 files big (attached,
preprocessed for x86-64).  Multidelta takes an enormous amount of time: after
~36 hours, it processed only first --level=0 run on four of the files, and
they're still massive after deltaing.  Thus, this test case is enormous, sorry.

Fails on amd64 with gcc-4.8 svn 194557 (Debian 4.8-20121217-1) and gcc-snapshot
(trunk), 4.7 works fine.  So does 4.8 on i386.
