This works on Unix 0.63.1, so no, you're not missing anything. Unless
you have something important redefined when you load your workspace.
To help debugging in, perhaps you could try something like:
hw.sum <- summary(lm(weight ~ height, data = women)) # avoids printing
hw.sum # I believe this provokes the error
traceback()
print.default(hw.sum)
debug(print.summary.lm)
hw.sum
