[Boost-users] [Context] Console output problem under Cygwin

Hi! Boost.Context examples (libs\context\example\v2) behave strangely under Cygwin/GCC-5.4.0. The problem is that all of the example applications output nothing to console. For example, jump_void.exe just ends at first "std::cout" command in execution context without any crash. This is the command line arguments I use to build both Boost.Context library and examples: b2.exe variant=debug link=static cxxflags="-std=c++14 -Wall -pedantic -D_GNU_SOURCE" Does anyone else ever met such a problem? Could it be a compiler bug or Boost.Context defect? Note: Under MinGW/GCC-4.9.3 all works OK. Thanks!
