Title:
  rpcgen: segfault when generating interfaces with argumentnames longer
  than 17bytes

Status in eglibc package in Ubuntu:
  Invalid

Bug description:
  Steps to reproduce:

  $ cat crashing_interface.x 
  program CRASHING_PROGRAM
  {
    version CRASHING_PROGRAM_VERSION
    {
      int api1(string looooooongArgument<>) = 1;
    } = 1;
  } = 0x20003ED7;

  $ /usr/bin/rpcgen -h crashing_interface.x 
  /*
   * Please do not edit this file.
   * It was generated using rpcgen.
   */

  #ifndef _CRASHING_INTERFACE_H_RPCGEN
  #define _CRASHING_INTERFACE_H_RPCGEN
  #include <rpc/rpc.h>

  
  #ifdef __cplusplus
  extern "C" {
  #endif

  Segmentation fault

  $ dpkg -S /usr/bin/rpcgen
  libc-dev-bin: /usr/bin/rpcgen

  If I make make the argument one byte shorter the segfault does not occur.
  Probably a buffer overflow when parsing the definition file.

  This problem appeared after the upgrade from maverick to natty.
