New issue 135 by [email protected]: Segfault when using omnicppcomplete/clang_complete
http://code.google.com/p/vim/issues/detail?id=135

What steps will reproduce the problem?
1. Use omnicppcomplete/clang_complete on a struct and C-n to skip to the next serveral alternatives

What is the expected output? What do you see instead?
When using gdb to debug vim, vim crashed here:
------
#5 0x0000000000442bc7 in ptr2cells (p=0x2b <Address 0x2b out of bounds>) at charset.c:764
764         if (enc_utf8 && *p >= 0x80)
(gdb) list
759     ptr2cells(p)
760         char_u      *p;
761     {
762     #ifdef FEAT_MBYTE
763 /* For UTF-8 we need to look at more bytes if the first byte is >= 0x80. */
764         if (enc_utf8 && *p >= 0x80)
765             return utf_ptr2cells(p);
766         /* For DBCS we can tell the cell count from the first byte. */
767     #endif
768         return (chartab[*p] & CT_CELL_MASK);
------

What version of the product are you using? On what operating system?
Plase see the bugreport.txt
Using Arch and everything should be up-to-date.

Please provide any additional information below.
The output of my gdb and bugreport.txt
Since the rebuild my vim to add the debuginfo, the core file is not needed.

Since the same segfault happens using tag based omnicppcomplete or clang_complete, the bug may not be in the plugins.
