I have been having random crashes of R from applying na.locf to xts
objects.

Going back after a crash and trying the same line again usually works;
then

a later, similar line will crash R again.

Has anyone seen this behavior?

 

It is sort of hard to send a minimal example because of the flakiness.

 

Sometimes the error Comes up in a Windows message box for MSV C++
Runtime Library, saying

'Runtime Error!

Program: ...\Rgui.exe

This application has requested the Runtime to terminate it in an unusual
way.

Please contact the application's support team for more information.'

Then R hangs and has to be killed.

Other times, the error come up in window for Visual Studio Just-In-Time
Debugger, 

saying that an unhandled exception occurred in Rgui.exe [6200].  (or
[5468] or [7220] or ...)

Going to Visual Studio yields Unhandled exception at 

0x6c80b097 [or 0x6c72b532 or ...]in Rgui.exe: 0xC0000005: Access
violation writing location 0x80000000 [or 0x00000043 or ...].

 

I can try to supply some more info if necessary, but as I said, the same
xts object will work the next time.

Thanks,

-- David
