[R] corrupted double-linked list

[Göran Broström]

Hello,

A weird thing happened to me while I was playing around in the R console 
with a data frame ('fert'). The finale was

-----------------------------------------------------
 > with(fert[fert$parity == 4, ], table(age, event))
          event
age         0   1   2
   (14,20]   0   0   0
   (20,25]   6  43  41
   (25,30]  57 565 513
   (30,35] 121 719 686
   (35,40] 165 309 317
   (40,45] 156  45  29
   (45,50]  13   0   0
 > fit1 <- coxph(Surv(exit - enter, event > 0.5) ~ strata(age) + civst + 
birthdate, data = fert[fert$parity == 0, ])
*** Error in `/usr/local/lib/R/bin/exec/R': corrupted double-linked 
list: 0x0000000004f1aa40 ***
Aborted
------------------------------------------------------
There was no .Rhistory file left (and my memory is too short) so I 
cannot reproduce it, but what is a "double-linked list"?

This is on Ubuntu 14.10 with  R  built from source.
