segmentation fault with chron.times()

I am running a simple R program, its skeleton is enclosed below.
The program reads about 80 files with about 5000 lines with coloumns of
data. After an unpredictable and variable number of loops for run to
run, it exits with segmentation fault or alternatively with the error

I had a similar problem and updated to the newest version of the chron
library. The error disappeared. Now I have a problem with cut.dates ...
(but already reported to Kurt Hornik, maintainer of the chron library)
