Hello,
I was trying to use get.hist.quote in tseries, and got a segfault:
-8<-----------------------------------
> library(tseries)
Loading required package: quadprog
Loading required package: zoo
'tseries' version: 0.10-6
'tseries' is a package for time series analysis and computational
finance.
See 'library(help="tseries")' for details.

This appears to be reproducible.
My R version is
platform powerpc-apple-darwin8.6.0
arch powerpc
os darwin8.6.0
system powerpc, darwin8.6.0
status
major 2
minor 3.1
year 2006
month 06
day 01
svn rev 38247
language R
version.string Version 2.3.1 (2006-06-01)
Is this a known issue?
Thanks,
Max
PS:
I can't seem to get useful info out of the dumped core:
Core was generated by
`/Library/Frameworks/R.framework/Resources/bin/exec/ppc/R'.
#0 0x90003568 in ?? ()
(gdb) bt
#0 0x90003568 in ?? ()
I guess I would need a version of R with debugging symbols in there?
