This line makes perl dump core:
perl -ne 'print unless split > 0'
This is the stack backtrace:
_make_op(8009ea88,2,8009ea88,800962c8,0) from 0x8005859e [ap = ffffc500]
_yyparse() from 0x80035aea [ap = ffffc8f0]
_main(1,ffffca20,ffffca28) from ___ap$envret+0x26 [ap = ffffca0c]
What I'm trying to do here is split $_ into @_
and count the fields. I had done this:
print unless split;
But that didn't seem to work either (but no core dump), even
though the man page states:
If not in an array context, returns the number of fields found and
splits into the @_ array.
So, Larry, is this a bug or am I confused?

Fixed in 42. The special code to parse the implied /\s+/ was clobbering
yacc's lookahead token subtype for >.

The latter bug seems to be unrelated. I can't reproduce it here on
any of my machines. It's either architecture specific or I've fixed it
already.
