3. The program crashes with a segmentation fault.
Actual Results:

Comment 4 Karl Lindén 2014-06-25 20:48:42 UTC
I tried the more recent versions in tree and the bug is reproducible with the following versions: 1.6.1, 1.7.1, 1.7.2. I do not know if the bug is reproducible with version 1.7.3, because it crashes with a segmentation fault much earlier.
Comment 5 Pacho Ramos gentoo-dev 2016-03-01 17:50:55 UTC
please retry with 2.0.3
