If there is a supported Boost.Build feature (is there?) to specify a maximum number of pending instantiations, we could even add this to the Jamfile for the test in questions.
There is such a feature, it has been added 6 days ago... feature.feature c++-template-depth : [ numbers.range 128 1024 : 128 ] [ numbers.range 20 1000 : 10 ] # Maximum template instantiation depth guaranteed # for ANSI/ISO C++ conforming programs. 17 : incidental propagated ; As a side note, this makes me wonder what the default value for this feature actually is? 128? And could the first range perhaps be modified to 64 1024 : 64? But anyway, I think that adding c++-template-depth=65 (Is 65 enough? 64 is not, 128 is for sure.) to the integer test is the best solution for this, provided that we add support for this feature to the acc and hp_cxx toolsets, which seems fairly easy. What do you think? Markus
