After winter holidays I returned to my project and noticed, that I am unable to profile code coverage when running unit tests like I did before. I tried running profiling with different configurations, however no one is working. When trying to perform profiling I just see my executable running and nothing more - no error messages, no code coverage window (.gcda and .gcno files are generated during compilation). I think this is caused by update from Oxygen to Oxygen.2, however I am not sure. Can you give me any advice on what should I do to make profiling work properly or to understand what is the root cause of such behavior?

Eclipse Version: Oxygen.2 Release (4.7.2)
Build id: 20171218-0600
MinGW compiler

It seems that was not eclipse, but MinGW error, because when I try running any command line utility it gave me error "0 [main] us 0 init_cheap: VirtualAlloc pointer is null, Win32 error 487". After I switched to the cygwin compiler and modified system path, so cygwin shell utilities are used everything is pretty OK.
