             Bug #: 54718
           Summary: [4.8 regression] ICE in remap_gimple_stmt, at
                    tree-inline.c:1468
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ro@gcc.gnu.org
                CC: dehao@gcc.gnu.org, ebotcazou@gcc.gnu.org
              Host: sparc-sun-solaris2.11
            Target: sparc-sun-solaris2.11
             Build: sparc-sun-solaris2.11


Since 20120921 (r191613), go fails to bootstrap on Solaris 11.1/SPARC:

/vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/expressions.cc: In member
function 'virtual bool
Type_conversion_expression::_ZNK26Type_conversion_expression24do_string_constant_valueEPSs.part.172(std::string*)
const':
/vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/expressions.cc:14226:1: internal
compiler error: in remap_gimple_stmt, at tree-inline.c:1468
 }
 ^

The failure can be reproduced with the attached expression.ii like this:

cc1plus -fpreprocessed expressions.ii -quiet -mcpu=v9 -g -gtoggle -O2
-fno-exceptions -fno-rtti -fno-common -o expressions.s


A reghunt revealed that this was caused by the following patch:
The first bad revision is:
changeset:   3438:f36a4197405d
user:        dehao@138bc75d-0d04-0410-961f-82ee72b054a4
date:        Wed Sep 19 19:56:42 2012 +0000
summary:     Integrate lexical block into source_location.

2012-09-19  Dehao Chen  <dehao@google.com>

        * toplev.c (general_init): Init block_locations.
[...]

The strange thing is that the failure only occurs on Solaris 11.1, not 11.0 or
10, but can be reliably reproduced on the former.  Maybe related to the VM
system rewrite in 11.1 in some way?
