That was my point too.

The crash that started this thread was introduced by this (recent) change:

2005-09-10  Giuseppe Scrivano  <address@hidden>

        Remove the MAXPATHLEN limitations:

        * sysdep.c (get_current_dir_name)
        [!HAVE_GET_CURRENT_DIR_NAME]:
        New function.

        * buffer.c (init_buffer): Use it.
                             ^^^^^^^^^^^^
                  This calls xrealloc on the result of get_current_dir_name ...
