The variable to turn on TI was uninitialized when alchemy was not on, so
it was probably starting out non-zero in some unpredictable set of cases.
I haven't actually reproduced the problem, but it should be fixed now.
Please test tomorrow after the nightly build and cvs update.
Thanks for reporting this.
