When testing boost 1.53, we saw an issue with config_test. It failed when using icl 14.0 beta. Q:\boost_1_53_0\libs\config\test>icl -TP /MDd /Zc:forScope /Zc:wchar_t /EHs -Od -DBOOST_ALL_NO_LIB=1 "-I..\..\.." confi g_test.cpp Intel(R) C++ Compiler XE for applications running on IA-32, Version 14.0.0.050 Beta Build 20130417 Copyright (C) 1985-2013 Intel Corporation.

The reason is the "__INTEL_COMPILER" is 1400 in 14.0 beta. After updating intel.hpp to following at line 183, the "config_test.ex" passed without issue: #if defined(__INTEL_COMPILER) # if (__INTEL_COMPILER <= 1110) || (__INTEL_COMPILER == 1400) || (__INTEL_COMPILER == 9999) # define BOOST_NO_COMPLETE_VALUE_INITIALIZATION # endif #endif Could you fix this issue in the trunk for future releases?
