[R] randomForest() segfaults under Solaris(SPARC) 2.7

Invocation of randomForest() using the iris example in the help
file crashes R with a segmentation fault. This happens on
all of our ultraSPARC machines running Solaris 2.7.

We're using R-1.4.1, compiled using Sun cc and f77 and
the flags:

CFLAGS="-xO5 -xlibmil -dalign"
FFLAGS="-xO5 -xlibmil -dalign"

"make check" runs withour errors, and R has been working
well for all other applications/installations.

Incidentally, randomForest() runs fine on one of our ultraSPARC machines 
running Solaris 2.6 and R-1.4.1 compiled using the same compilers and flags.
It also reportedly works if gcc/g77 are used.

Any suggestions appreciated.
