Reason: inconsistent compilation, federatedx is compiled without SAFEMALLOC flag, while anything else is compiled with SAFEMALLOC. As a consequence, my_hash_init used inside federatedx initialization does not provide correct caller info parameters (file, line) , so they are initialized with whatever is on stack. When info about allocated memory is output in COM_DEBUG command, the server crashes trying to output string starting at 0xcccccccccccccccc. The fix is to remove SAFEMALLOC preprocessor flags from every CMakeLists.txt, except the top-level one. Also, SAFEMALLOC is not defined by default now, instead there is WITH_DEBUG_FULL CMake option which adds -DSAFEMALLOC to C and C++ flags in debug compilation. This option is off by default, because 1) Debug C runtime already has heap debugging builtin with overwrite and leak detection 2)safemalloc considerably slows down the tests. Note also that - SAFEMALLOC is gone in MySQL5.5 - On Windows, heap related overflows can also be found using free pageheap utility (that is also part of application verifier). This is even more efficient if there are no other layers on top of Windows heap allocator, e.g it is most efficient with release version.
