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
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
