R help - Sep 2004 - RSPerl Causes Segfaults with Perl 5.8.0 and R 1.9.1 on Redhat9

RSPerl causes random segfaults (it occassionally works) in
Rf_isValidName () from /usr/lib/R/bin/libR.so when I call wilcox.test
on some perl array references.  This is with R built from the
r-project source RPM modified to have the --enable-shared-R option and
RSPerl built with the default options, except for having to set
PERL_MODULES to not include modperl or Apache.

any ideas?
eric.
