segmentation fault in Info's regexp search when typing backslash

[Marco Maggi]

Hello,

  I'm on a x86_64-slackware-linux-gnu, running Texinfo 6.4:

   $ info --version
   info (GNU texinfo) 6.4

while  reading  a  file  with  info,  no matter  which  file,  I  get  a
segmentation  fault when  typing C-s  \, which  is the  command entering
"Regexp I-search" followed by a backslash:

  regexp error: Trailing backslashSegmentation fault

I can say that it does not happen when using Info 6.1.
