Binary search is a great idea, especially for a bug that vanishes with the debugger operating.

In addition to the possibility of a timing bug, it sounds to me like it might be a memory leak or buffer overflow problem. Without debugging, the leak may trample some useful code and cause the bug. The debugger may move things around so that the leak overwrites some less harmful memory location. In that case, adding print statements might also affect what areas the leak overwrites and cause the bug to vanish from the modified code.

I binary search can hardly be underestimated in its efficiency of reproducible bugs... Theory is your friend... I love it, if there is no faster plan.
