[Rd] editing pasted text from parameter list through rcompletion crashes R in Windows (PR#9775)
Full_Name: Michael Toews
Version: R 2.5.1
OS: WinXP; SP2
Submission from: (NULL) (142.58.206.114)
To reproduce this crash:
1. Start a new R session normally in Windows
2. Type (an example command): "boxplot(" without pressing enter
3. Copy this text: "c(1,2,6,4,7,3)"
4. Bring Rgui.exe back in focus, and hit "Tab" twice to activate the
parameter
list (you should see "x= ...= range= width="
etc.)
4. Paste the text, then press the backspace key, *crash*
There several other variations to crash R similarly, such as pressing the
left-key to edit the pasted text while rcompletion is showing the parameter
list. Present behaviour for rcompletion is to remove the parameter list from the
console after typing has started; however, this list is not removed if text is
pasted, which appears to crash R if the cursor moves backwards (buffer
problems?).
