Never mind - you did in your first e-mail. But from that info it is clear that you're not using CRAN R, so I fear we can't really help you since this problem is specific to your own R build. You should try the R release on CRAN to see if you can reproduce it with that. If not, you may want to use gdb to trace the issue (R -d gdb) - it could be R or some library you're using ... If you want us to look int that, you'd have to provide exact details on how you compiled that R (compiler versions, configure flags etc.).

Cheers,
Simon

My .bashrc sets R_LIBS and the usual additions to the default PATH, nothing that should affect R or x11. Since I haven't heard back a flood of people saying, 'yes, me too', I suspect, this issue is specific to my setup. I've tried clearing out any preference files related to x11, to no affect. When calling plot (1:10), I get a new x11 graphics window, ten circles and an x-axis with tick-marks, and a segfault. No box(), no y-axis. There's no .Rprofile in my home directory. Are there any other preference files that could be corrupted?
