Stack overflow when parsing 20k consecutive + signs #415
Description
I accidentally left the headphone on the keyboard on the + button.
I just pressed enter and Julia hung for a while, at 100% and mem. use seemingly growing. It's not a big deal since it recovered (might not for others, and OOM?), I'm just thinking if something can be imrpvoed.
