Comment (by maldun):
Typing
{{{
chebyshev_T(1000000,x)
}}}
in the old version gives a proper result in 7.52
The exact same input gives me full memory (8GB on my machine) and about
1GB swap + a frozen system in the new version.
Higher input gives a an error of flint (Memory allocation error)
Some switch would be nice
