JSMin: Unterminated RegExp

[ficike]

Hello!

I got an interesting error when trying to compress the following js code snippet:

opt.t = opt.tstart * (1 - i++/(times -1));

Exception:
UnterminatedRegExpException
JSMin: Unterminated RegExp at byte 406780: /(times -1));

I tried to fix it by splitting the calculations into smaller variables to avoid parentheses but it didn't help.
It always looked like a regular expression for the division sign.
