@dkasper26 I just tried reproducing this on a 144 CPU el7 machine, but htop runs without issues there. Tried both the 2.2.0 release and master branch, both ran fine.
I did have to build with --disable-unicode since addnwstr is not present in libncurses[w] there - perhaps the problem could be related? The gdb header from your report also points this way.
Could you provide the rest of the stack trace? ('bt' at your gdb command prompt)
And also as another data point try a build with Unicode to see if the problem goes away?
