3	incomplete-gamma-tail very slow near the negative real axis	rtoy	somebody	"Evaluation of {{{incomplete-gamma-tail}}} is very slow near the negative real axis.  For {{{(incomplete-gamma-tail 1/2 #c(-100 1d0))}}}, we get an answer quickly.  But replace that with {{{#q(#q-100 #q1)}}} and Oct now takes a long time.  Change it to {{{#q1q-1}}} instead of {{{#q1}}}, and Oct takes forever.  

It's stuck in computing the continued fraction in {{{CF-INCOMPLETE-TAIL}}} which isn't valid on the negative real axis."	defect	new	major		Core
