For solving the same problem on my compiler I use something like the
chunk of code below. It works fine on Windows XP, although in one case
it still pops the dialog on Vista/7. I didn't investigate the issue but
it is probably a missing _CrtSetReportMode call. Maybe it is worth a try
before adding yet another utility.

#include <signal.h>
#include <stdio.h>
#include <stdlib.h>

#if defined(_MSC_VER) && ! defined(NDEBUG)
# include <crtdbg.h>
#endif

#if defined(_WIN32)
# include <windows.h>
#endif

void InstallSignalHandlers();

#define SIGNAL_ARGS int sig

void sig_abrt_catcher(SIGNAL_ARGS);
void sig_ill_catcher(SIGNAL_ARGS);
void sig_fpr_catcher(SIGNAL_ARGS);
void sig_segv_catcher(SIGNAL_ARGS);

int main() {
  /* ... */
  InstallSignalHandlers();
  /* ... */
}

void InstallSignalHandlers() {        
  signal(SIGFPE, &sig_abrt_catcher);
  signal(SIGFPE, &sig_ill_catcher);
  signal(SIGFPE, &sig_fpr_catcher);
  signal(SIGSEGV, &sig_segv_catcher);
#if defined(_MSC_VER) && ! defined(NDEBUG)
  _CrtSetReportMode(_CRT_ASSERT, _CRTDBG_MODE_FILE);
  _CrtSetReportMode(_CRT_ERROR, _CRTDBG_MODE_FILE);
  _CrtSetReportHook(&MsvcrtReportHook);
  _set_error_mode(_OUT_TO_STDERR);
#endif // #if defined(_MSC_VER) && ! defined(NDEBUG)
#if defined(_WIN32)
  SetUnhandledExceptionFilter(&UnhandledWin32Exception);
#endif
}

void sig_abrt_catcher(SIGNAL_ARGS) {
  puts("SIGABRT\n");
  exit(3);
}
  
void sig_ill_catcher(SIGNAL_ARGS) {
  puts("SIGILL\n");
  exit(3);
}

void sig_fpr_catcher(SIGNAL_ARGS) {
  puts("SIGFPR\n");
  exit(3);
}

void sig_segv_catcher(SIGNAL_ARGS) {
  puts("SIGSEGV\n");
  exit(3);
}
