C++ Source Code
Hello,
This code compiles correctly on Clang 3.0, but fails on Clang 3.1. The broken
code needs to be built with -O1 atleast. I believe it only fails when the
compiler was built with optimizations on.
I'm using Linux x86_64 Centos 5. The test case also requires the boost
libraries, and I'm using version 1.49.0 of that. It uses a header only library,
so the attached preprocessed code can be used on machines that don't have it
preinstalled.
The code is:
#include <boost/spirit/include/lex.hpp>
#include <boost/spirit/include/lex_lexertl.hpp>
typedef boost::spirit::lex::lexertl::actor_lexer<> lexer_type;
int main() {
boost::spirit::lex::lexer<lexer_type> l;
l.self += boost::spirit::lex::token_def<>(".") [boost::phoenix::val(1)];
}
When compiled under clang 3.0, there are no errors.
[8:42pm][wlynch at apple clang] /opt/llvm/3.0/bin/clang++ -c -O1 -I
/opt/boost/1.49.0/include lexer.cpp
[8:43pm][wlynch at apple clang] echo $?
0
When compiled under clang 3.1, there is an ICE.
