Bug #: 56268
Summary: [4.7/4.8 Regression] C++11 ICE with boost
multi-precision and boost variant during assignment
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
Created attachment 29402

Sample code to reproduce the problem
This issue is quite similar to bug 55842.
Compiling the attached sample file leads to an internal compiler error.
The problem only occurs with GCC-4.7 from Debian Unstable 4.7.2-5 and the
upcoming 4.8 from Debian Experimental 4.8-20130127-1. Tested on an amd64
system. (GCC 4.6 works, properly.)
I'm using a checkout of the latest boost release tree.
The command to reproduce the issue is:
gcc-4.8 -std=c++11 -c -I/src/boost/release test.cpp
