qchisq behaves very strangely when ncp is passed as zero (forcing internal qnchisq to be called) when first argument is small.

Eg

> qchisq(1-1e-6, 1, ncp=0, lower.tail=TRUE)
qchisq(1-1e-6, 1, ncp=0, lower.tail=TRUE) [1] 1024

while, if ncp is unspecified,

> qchisq(1-1e-6, 1)

qchisq(1-1e-6, 1)
[1] 23.92813
