Subject: segfault during snarf-check-and-output-texi on x86_64-darwin11
 (guile-2.0.9)
Date: Tue, 29 Oct 2013 17:31:23 -0400 (EDT)

Hi guile team,

platform: x86_64-darwin11 (OS 10.7)
compiler:
Apple LLVM version 4.2 (clang-425.0.28) (based on LLVM 3.2svn)
Target: x86_64-apple-darwin11.4.2
Thread model: posix

CFLAGS: -g -O2
configured with options "'--prefix=/sw' '--infodir=/sw/share/info' 
'--program-transform-name=s|guile|guile-2.0|g' '-C'"

I've been unable to build guile-procedures.texi due to a segfault while 
guild-snarfing .doc files.  About half of the .doc files in 
$(builddir)/libguile can trigger the segfault when redirected to 
guild snarf-check-and-output-texi.

debug session here: http://paste.lisp.org/display/139704

Here's a gdb stacktrace:

More data points:
For guile-2.0.9 also tried building:

x86_64-darwin11, Apple-clang from Xcode-4.6.2 (same as original report) with -g -O1
	also seg-faults

x86_64-darwin11, clang-release-3.3 with -g -O2
	also seg-faults

powerpc-darwin8, Xcode 2.5, apple-gcc-4.0.1 with -g -O2
	works fine

On x86_64-darwin11 (clang-built, -g -O2), the exit status of the failure 
is not even consistent from run-to-run, nondeterministic behaviour!

This problem went away by fixing the gc library (which had failed tests 
before).
