I tried to solve an equation numerically, using Ginsh from the git repository. When entering
fsolve((1/(sqrt(2*Pi)))*integral(t,0,x,exp(-1/2*t^2))==0.5,x,0,100)
into Ginsh, it crashes, see below. I got the same problem with the version shipped with the latest stable Ubuntu Linux.
I've posted patches which should fix this bug to ginac-devel (the combined patch is attached for convenience). Could you please check if they work for you?
Best regards, Alexei
