bug that causes python to use 99% of the cpu

[jiun]

it seems there is a bug that causes python to spike in cpu usage for some inputs,
here is one case that i ran into:

>>> a =u'(%o10) log(x^2-x+1)/6+atan((2*x-1)/sqrt(3))/sqrt(3)-log(x+1)/3'
>>> import asciitomathml.asciitomathml
>>> the_string = a
>>> the_string = unicode(the_string.decode('utf8')) # adjust to your own encoding
>>> math_obj =  asciitomathml.asciitomathml.AsciiMathML()
>>> math_obj.parse_string(the_string)

after this the computer get so overwhelmed i have to do a hard restart, since it becomes totally unresponsive.
this is a serious one.

I've fixed the bug and the newest version, .88, should now work.

By the way, couldn't you just use ctr-C to quit out of your shell rather
than having to do a hard restart on your computer?

I fixed the bug. By the way, can't you just use ctr-c to force the program to quite from the shell, rather than doing a hard restart?

Thanks for the fix, apparently sourceforge does not give nottifications.
But, when the usage spiked, even the keyboard+mouse was unresponsive, there was no way for me to kill the process.
