We need to know a great deal more information, and asking on R-devel would
be a lot kinder than blaming this on a bug in R (and please use a
meaningful subject line).
What version of R is this?
Precisely what OS (Solaris 9 comes for several architectures)?
Assuming you compiled R yourself, what compilers did you use? (And where
did you get those from if they are not Sun compilers?) If got a
pre-compiled version, you need to try compiling on the machine you are
Do you have a debugger for your compiler? If so you can run R under the
debugger (possibly R -d gdb) and debug the crash for yourself. (We cannot
do this for you unless we can reproduce it.)
Given that Solaris 9 is long obsolete (Solaris 10 is more than 3 years'
old), we don't hear of many R users on it. But we do hear from some using
it successfully. And since R is in use on both Solaris 8 and 10, it is
unlikely to be a generic Solaris issue.
Given all our experience, the most likely explanation is a bug in the
software on your machine, e.g. in a compiler. Please take this to your IT
support team and get them to identify the problem -- if they are able to
supply a patch to a current version of R that works around the problem it
would be a positive contribution to the R project.
