This is caused by the binary being compiled with the VC++ compiler option
"Basic runtime checks" set to detect uninitialized variables.

Just press the ignore button....

mysys/my_init.c should have a new function like this:

#ifdef __MSVC_RUNTIME_CHECKS
#include <rtcapi.h>

/*
  handle_rtc_failure
  Catch the RTC error and dump it to stderr
*/

int handle_rtc_failure(int err_type, const char *file, int line, const char* module,
                       const char *format, ...)
{
  va_list args;
  va_start(args, format);
  fprintf(stderr, "Error at %s:%d: ", file, line);
  vfprintf(stderr, format, args);
  fprintf(stderr, "\n");
  va_end(args);
  (void) fflush(stderr);

  return 0; /* Error is handled */
}
#endif

and it should be installed in 'my_win_init'

#ifdef __MSVC_RUNTIME_CHECKS
  /*
    Install handler to send RTC (Runtime Error Check) warnings
    to log file
  */
  //_RTC_SetErrorFunc(handle_rtc_failure);
#endif

that will take care of sending and left over CRT errors to the the error log
