shared_ptr to bool cast with Intel C++ Composer XE 2011

[abrarov@…]

shared_ptr-to-bool cast sometimes doesn't work on Intel C++ Compiler 11.1.

As test ​asio-samples project may be used. Watch at svn repository for the echo_server project: /src/ma/echo/server/session_manager.cpp:151. The "while" cycle doesn't work right (cycle works when shared ptr "active_session" points to nothing) without the suggested patch.

Can you please attach a simple test case?

I tried to provide a simple test case but it's not so simple (simple tests passes well).
Even in echo_server at some places Intel C++ Compiler works well (but failes in many places too).
The echo_server project is rather simple - it uses only Boost C++ Libraries and "standard" MS Windows headers. So it is rather simple to build it (from MS Visual Studio with integrated Intel C++ Compiler - use /build/intel11/asio-samples.sln).
Make test without patch and within it - and You'll see the difference.

It seems (working with Boost 1.46 with

#undef BOOST_NO_RVALUE_REFERENCES

added to boost/config/compiler/intel.hpp) that compiler option (added from Commind Line memo in project settings) /vmg is the source of problem.

I will update ​asio-samples project in a week to provide public access to Intel-Compiler-12-based projects.

Turn on rvalue referense support in Intel C++ Compiler 12

Done. Project "echo_server" works fine with ICC 12.x and suggested patch and crashes because of shared_ptr-to-bool cast (src/ma/echo/server/session_manager.cpp: line 316) without patch.

Problem showing test

[abrarov@…]

Test environment:

1. Windows 7 Ultimate x86 Russian.
   
2. MS Visual Studio 2010 SP1.
   
3. Intel C++ Composer XE 2011 update 7.

See cpp_test.zip attachment for test showing problem in debug mode only. Note /vmg compiler option (not needed for MSVC 10.0, but required for Intel C++ Composer).

Test environment:

4. Boost C++ Libraries 1.49.0

Related bug #8152.

I am seeing the same issue with MSVC-9 and MSVC-10 compilers. The shared_ptr to bool conversion is causing write access violations when using the /vmg option. This looks like a compiler bug to me, as I reproduced it with the standard safe bool idiom implementation on a simple class.

[Ross MacGregor <rossmpublic.gmail.com>]

My problem with the MSVC compilers turned out to be a binary incompatibility issue. I was using the pointers_to_members pragma but I did not apply it carefully enough (which looks rather difficult). I ended up with multiple member references using different internal representations. I violated the one definition rule.

This also may be the cause of this problem too. Maybe the /vmg option is not being consistently applied for the same smart pointer types?

Closing as too old and possibly no longer relevant.
