[R] error using try() and coxph()

Dear all,
I'm experiencing some problems in using the following code to perform
simulations with Cox models (using coxph() in survival package):

for(i in 1:1000){
    dd<-....#simulate the dataframe

The error (both in Rgui and in batch mode) causes R to crash immediately
with a DOS message like "Error in survival.dll"
Using coxph() without try() simulation stops because sometimes the model may
be not fitted, I get the explicit error message. Therefore I suspect that
the problem depends on using try(coxph(....)). Also note that using
try(arima(....)) for a similar problem works well.
versions: survival 2.9-4 and R 1.5.1 on WinMe
I know I should update R, but I wonder whether the problem depends on the
old version

Could anyone suggest me anything?
