[Bug c++/24190] New: ICE using optimization

["Thomas dot Svedberg at chalmers dot se" <gcc-bugzilla at gcc dot gnu dot org>]

ICE on compiling the following:
#include <string>
#include <boost/algorithm/string.hpp>

void __prepare_line (std::string & line, const char * linebuf)
{
        line = linebuf;
        boost::erase_last (line, "\r");
}

> gcc-4.1.0 -v

Target: i686-pc-linux-gnu
Konfigurerad med: ../4.1/configure --enable-languages=c,c++,f95 --enable-shared
--enable-threads=posix --disable-checking --program-suffix=-4.1.0
Trådmodell: posix
gcc version 4.1.0 20051004 (experimental)

> g++-4.1.0 -O1 -c -O GCC-BUG.cpp
GCC-BUG.cpp: In function "void __prepare_line(std::string&, const char*)":
GCC-BUG.cpp:4: internal compiler error: Segmenteringsfel

I have seen this for some time, same results with O2 or O3 (works with -g).
