otpcalc-0.97 terminates with segmentation fault when the "Calculate" button is pressed. The bug is always reproducible on some of the x86 computers here (on some others it doesn't occur). The problem is at the beginning of function calculate() in file callbacks.c, where hashes[4] is defined but 5 elements are assigned. A patch for the ebuild is attached.
Created attachment 80619 [details, diff] Proposed patch for otpcalc-0.97.ebuild
The problem is completely unrelated to bug #123950 reported earlier today, of course.
fixed in 0.97-r1, well spotted :)
