qnbinom with small size is slow
Hi all,
I recently noticed that `qnbinom()` can take a long time to calculate
a result if the `size` argument is very small.
For example
qnbinom(0.5, mu = 3, size = 1e-10)
takes ~30 seconds on my computer.
I used gdb to step through the qnbinom.c implementation and noticed
that in line 106

qnbinom with small size is slow
?? I can reproduce this on
R Under development (unstable) (2020-07-24 r78910)
Platform: x86_64-pc-linux-gnu (64-bit)
Running under: Pop!_OS 18.04 LTS
? In my opinion this is worth reporting, but discussing it here first
was a good idea.? Many more people read this list than watch the bug
tracker, so it will get more attention here; once the excitement has
died down her...

I have also requested a Bugzilla-account, but haven't heard anything back yet.
Best,
