The backtrace indicates that the non-working version has multibyte
disabled.  I.e., it looks like YY_INPUT invoked zend_stream_read,
which means that ZEND_MULTIBYTE was not defined.  This is the default,
and it is how I configured php5.  I didn't observe the bug.

I also tried configuring php5 with "configure --enable-zend-multibyte",
but couldn't reproduce the bug that way either.
