[Rd] Bug report: 'formula("x")' loops infinitely ('formula("y")' does not)

[P Poncet]

Dear,  

The script'formula("x")' loops infinitely. More specifically, it throws thefollowing error: 

 

Error: evaluationnested too deeply: infinite recursion / options(expressions=)? 

 

As a side effect,this makes an IDE like RStudio to crash. 

On the other hand,the script 'formula("y")' works as expected : if ‘y’ does notexist in the global environment, it throws: 

 

Error ineval(parse(text = x, keep.source = FALSE)[[1L]]) : object ‘y’ not found

 

I use R-3.6.0 onWindows. 

 

Bestregards, 
Paul Poncet
