Description Andrius Štikonas 2014-05-30 18:21:58 UTC 
KBruch asked the following question:

5/9 + (1 1/3) / (1 1/2) - 6 - 2

The correct answer should be -6 5/9 but KBruch claims that correct answer is 1.

Reproducible: Didn't try

Actual Results:  
KBruch claims that answer must be 1.

Expected Results:  
KBruch claims that correct answer is -6 5/9.

All the check boxes on the left were enabled. Number of terms was 5. Maximum denominator was 50.

I think reproducibility of this can be checked if source code is modified so that it always creates this problem instead of the random one.

Note that I also encountered some infinite loops while trying to reproduce this manually...

Just saw this bug now. I haven't touched the code since years, so need to investigate who broke it. This used to work for more than 10 years without problems :-(

I believe this problem was fixed by not allowing to select both checkboxes: mixed numbers and reduced results.

I was not able to reproduce this bug anymore compiling latest version from master branch.
