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...]
In end of data:
cedet/srecode/table.el:291:1:Warning: the function `srecode-mode-table' is not
known to be defined.

What happens if you build with debugging enabled?
It might help to turn off optimization, so that you
can debug the thing. Something like this, maybe?
./configure --without-x --with-ns --enable-checking CFLAGS='-g3 -O0'

I tried that, and unfortunately the problem does not occur when compiled -O0.

How about configure with --enable-checking -- do you
still get the same symptoms, or (hope, hope) do you get
an assertion failure? Also, for better debugging you might
try CFLAGS='-g3 -O2 -fno-crossjumping' instead of plain -O2.

I did this, but the problem did not occur. Getting suspicious, I tried a build on head with exactly the configuration that was failing for me before, and it no longer fails. But, if I check out the tag after the cedet integration that I mentioned in my bug report, it still does fail. So, something changed between the time I reported the bug and head that either fixes the problem or obscures it again :)
If you want to declare victory, that's OK with me, but I'm a little curious still so I'll try doing a build with the configuration you suggested against a version that fails. I will report if anything interesting happens.

Certainly the GNUstep port has seen changes since then.
I'm mildly inclined to declare victory, since it works for you now.
We can always reopen the bug if it comes back. But if you'd
like to debug the broken version, I suggest compiling with
-fno-omit-frame-pointer as well, like this:
./configure --without-x --with-ns --enable-checking CFLAGS='-g3 -O2 -fno-crossjumping -fno-omit-frame-pointer'

I vote for closing the bug. I rebuild from head every few days, so if anything crops up again I'll investigate further and reopen the bug.
Thanks,

I tried compiling the broken version with --enable-checking and CFLAGS='-g3 -O2 -fno-crossjumping'. It segfaulted in the same place and was still not easily debuggable due to optimization.
