Odd.. usually the situation is the reverse.

But if I am to guess then my guess it that you have placed some required
logics into a debug() statement somewhere.. debug() statements must be
written without any sideeffects or things will behave differently if
debugging is enabled or not.

Using a debugger such as gdb usually helps finding this type of problems

  gdb /path/to/sbin/squid
  run -DNYCd3

valgrind is also quite helpful. (http://valgrind.kde.org/)
