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: unassig...@gcc.gnu.org
ReportedBy: r...@gcc.gnu.org
CC: de...@gcc.gnu.org, ebotca...@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 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?
