This means that you built this testcase with MinGW or with -mno-cygwin, which means that these implementations of malloc, realloc, etc. are handled by the Microsoft C library (MSVCRT). You essentially are not using any part of Cygwin here, so any behavior of the heap and/or memory allocation and/or any other standard C funtion that you call is not our code that's running, so it's pretty much off-topic for this list. The MinGW list might be better.
