Executing inline code crashes RStudio Preview

[Impetus]

I tried two different preview versions of RStudio 1.4x and both always crashed if one had the following line in an RMarkdown document, put the cursor in-between the 4 and the +, and pressed CTRL ENTER:

Note that the echo = FALSE parameter was r 4+2 added to the code chunk to prevent printing of the R code that generated the plot.

Now, back with 1.3.1093, this problem is gone. Here's the output of sessionInfo()

@Impetus

if one had the following line in an RMarkdown document,

I don't see the lines in questions and the Rmd chunks in your post. Did I missed something ?

[Impetus]

Oops, so sorry, that must have beena copy-paste error. I actually just meant any line with inline code like this:

abc def ghi r 2+2 jkl.

I can't reproduce this. Let's wait tomorrow for the new daily, and you'll tell us if it is fixed.

Ok, I'll check it out, thanks!
