R devel - Feb 2004 - Segmentation fault with fix() (PR#6605)

Full_Name: Federico Gherardini
Version: 1.8.1
OS: Gentoo linux
Submission from: (NULL) (81.208.36.89)


When I use fix() to edit a matrix R immediately quits with a segmentation fault
if I use the copy button in the graphical device window. Clicking on the name of
the variables completely  messes up the screen too. In this case you have to
close the grahpic device and call fix() again.
I've compiled R from sources on a pentium4 with these falgs:
CFLAGS="-march=pentium4 -O2 -pipe -msse -msse2 -mmmx"
CXXFLAGS=CFLAGS
and on a Celeron (Mendocino) with these:
CFLAGS="-march=i686 -O2 -pipe -mmmx"
CXXFLAGS=CFLAGS
and I've also tried to use both nano and vim as editors. In each case I
always
get the same error on both computers

Confirmed on r-devel/Opteron and 1.8.0/K6, so it has likely been with
us for a while. Goes to show how much people actually use that
interface...

(You didn't quite give reproducibility instructions, but 

data(women); fix(women)

and then press Copy etc. will do it.)

BTW, the messed-up screen can be worked around by minimizing and
unminimizing the window.
