Using malloc/realloc along with gdb: heap overflows

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.
