infinite uninterruptible hang on one illegal input to ftest

[xgdgsc]

ftesthang.csv

using CSV
using GLM
using DataFrames
regData = CSV.read("ftesthang.csv", DataFrame)
ols = lm(@formula(Y ~ X1 + X2 + X3 + X4 + X5 + X6 + 1), regData)
oCoefs = coef(ols)
ftestRes = ftest(ols.model)

With this illegal input. ftest hangs in an infinite uninterruptible way. Is it possible to throw an error instead?

Looks like the continued fraction implementation of the incomplete beta function in SpecialFunctions gets stuck in an infinite loop because there's no check that the input is finite.

Okay! That's a pretty degenerate case. This is now fixed upstream.
