This report describes two similar, but different scripts causing segmentation fault in R-2.1.1 and R-patched_2005-08-21.

The first is a script that causes segmentation fault in R-2.1.1. Although the script runs correctly under R-patched_2005-08-12 and R-patched_2005-08-21, there is still a reason to investigate the bug in more detail.

The second is a slightly different script that causes segmentation fault in R-patched_2005-08-12 and R-patched_2005-08-21 (I did not try the intermediate versions).

Both bugs were observed under two different installations of RedHat: 1. Fedora Core release 2 (Tettnang)

   with gcc (GCC) 3.3.3 20040412 (Red Hat Linux 3.3.3-7), 2. Red Hat Linux release 9 (Shrike)

   with gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)

In both cases, the compilation used the default settings. If the compilation used ./configure --with-readline=no --with-x=no then the bugs did not appear.

I did not succeed to reproduce any of the bugs under SuSE 8.2 with gcc (GCC) 3.3 20030226 (prerelease) (SuSE Linux).

In the installations, where the bugs occur, they are reproducible deterministically.
