infinite loop in jom.exe

on some machines (~15%), when I run jom.exe it freezes and becomes stuck in an infinite loop consuming CPU in the kernel space. The loop is occurring very early on, even prior to hitting isSubJOM(QString) check. If I add some delay in the program by adding a few printfs to the main() and recompile it will work correctly on the machine it was previously failing on.

int main(int argc, char* argv[])
{
qDebug("Hello, this is line one of jom.exe main");

SetConsoleCtrlHandler(&ConsoleCtrlHandlerRoutine, TRUE);
qDebug("After SetConsoleCtrlHandler method");
Application app(argc, argv);
qDebug("After Application init");
QTextCodec::setCodecForLocale(QTextCodec::codecForName("IBM 850"));
