bug#14587: Segfault compiling cedet/srecode/texi.el during "make bootstrap"

[Bob Halley]

Since the recent CEDET merge, Emacs no longer builds for me.  It segfaults
while compiling cedet/srecode/texi.el.  The fault happens on optimized builds
with both gcc 4.2.1 and clang from the most recent Xcode (4.6.2) OS X.

If I checkout something just before the sequence of CEDET merges that ended
with

commit 8a705018438ec0142e964a48f1af4996242e20f6
Merge: 509f7cc 5419570
Author: David Engster <dengste@eml.cc>
Date:   Sun Jun 2 18:39:32 2013 +0200

    Merge with CEDET upstream (rev. 8564).

everything builds fine.  Any version at or after the version above fails.

Details:

(x86_64-apple-darwin12.4.0, NS apple-appkit-1187.39)
 of 2013-06-02 on bark.local
Windowing system distributor `Apple', version 10.3.1187
Configured using:
 `configure --without-x --with-ns -with-wide-int'

$ make bootstrap

[...all is good until...]

271                   ptrdiff_t nbytes = len + directory_nbytes + needsep;
272                   ptrdiff_t nchars;
273     
274                   fullname = make_uninit_multibyte_string (nbytes, nbytes);
275                   memcpy (SDATA (fullname), SDATA (directory),
276                           directory_nbytes);
277     
278                   if (needsep)
279                     SSET (fullname, directory_nbytes, DIRECTORY_SEP);

I don't know how to debug this, but if you tell me what you need I can
try to do it!
