You need to set a break point at 0x100eea5b0 and run again until that break is
hit, then start stepping.

Nick,
   I will try one other thing first. I'll rebuild gcc47 without graphite
support so cc1 has no linkages on cloog/ppl/isl
and the test it against a stock build of llvm32 to see if this suppresses the
error.

Nick,
    We can eliminate the linkages of ppl/isl/cloog in cc1 as the cause of the
problem. I rebuilt the gcc47 package with...

Configured with: ../gcc-4.7.2/configure --prefix=/sw --prefix=/sw/lib/gcc4.7
--mandir=/sw/share/man --infodir=/sw/lib/gcc4.7/info
--enable-languages=c,c++,fortran,lto,objc,obj-c++,java --with-gmp=/sw

--with-system-zlib --x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib
--program-suffix=-fsf-4.7

to disable the graphite support such that cc1 is linked as...

% otool -L  /sw/lib/gcc4.7/libexec/gcc/x86_64-apple-darwin12.2.0/4.7.2/cc1 
/sw/lib/gcc4.7/libexec/gcc/x86_64-apple-darwin12.2.0/4.7.2/cc1:

	/sw/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)
	/sw/lib/libmpc.3.dylib (compatibility version 4.0.0, current version 4.0.0)

	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version
169.3.0)

Using a dragonegg.so plugin built against this compiler, still produces the
error...

when loading the /sw/opt/llvm-3.2/lib/LLVMPolly.so plugin. This is as much as I
can reduce
the cc1 linkages so I'll have to manually hunt for the symbol now. Sigh.

Nick,
   If I set 'break *0x100eea5b0', I didn't get any output from
DYLD_PRINT_BINDINGS being set.
However if I set the breakpoint at PluginLoader.cpp:29 which is near the loading
of LLVMPolly.so,
I get...

....

The complete log is uploaded to http://llvm.org/bugs/attachment.cgi?id=9397 of
http://llvm.org/bugs/show_bug.cgi?id=14140.
I would also note the following...

1) cc1 doesn't appear to be linked against any libstdc++.

/sw/lib/gcc4.7/libexec/gcc/x86_64-apple-darwin12.2.0/4.7.2/cc1:
	/sw/lib/libintl.8.dylib (compatibility version 10.0.0, current version 10.1.0)
	/sw/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)
	/sw/lib/libmpc.3.dylib (compatibility version 4.0.0, current version 4.0.0)
	/sw/lib/libmpfr.4.dylib (compatibility version 6.0.0, current version 6.1.0)
	/sw/lib/gmp5/libgmp.10.dylib (compatibility version 11.0.0, current version
11.5.0)
	/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version
169.3.0)

whereas libPolly.so is always linked against the system libstdc++ shared
library...

/sw/opt/llvm-3.2/lib/LLVMPolly.so:
	/sw/lib/libisl.10.dylib (compatibility version 11.0.0, current version 11.0.0)
	/sw/lib/gmp5/libgmp.10.dylib (compatibility version 11.0.0, current version
11.5.0)
	/sw/lib/libcloog-isl.3.dylib (compatibility version 4.0.0, current version
4.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version
169.3.0)
	/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version
56.0.0)

2) The problem seems to be immune to which libstdc++ shared library that
/sw/lib/gcc4.7/lib/dragonegg.so
is linked against. I have built dragonegg both with the FSF gcc-fsf-4.7 compiler
to link in
the FSF libstdc++ as well with clang to use the system libstdc++. Both modes of
building LLVMPolly.so
produce the same fast lazy binding failure.

Any suggestions on where to go from here in debugging this?

Nick,
   Can you clarify what I should be looking for here? I assumed you expected
that I should see some symbol
bindings occur immediately after the initializer function in LLVMPolly.so is
called but before dyld throws
the "fast lazy bind offset out of range" error message. In the
http://llvm.org/bugs/attachment.cgi?id=9397,
the log file for a walk with DYLD_PRINT_INITIALIZERS and DYLD_PRINT_BINDINGS set
on darwin12, I only see...

where all of the bindings from LLVMPolly.so occur before the initializer

expected?
   Also, as I noted on http://llvm.org/bugs/show_bug.cgi?id=14140#c13, a static
build of LLVMPolly.so on 10.6 exhibits the
same dyld error. Am I correct to assume that test proves that the offending
symbol can't be from libcloog-isl, libisl,
libgmp or libstdc++ because, when statically linked, those symbols can't be
obtained from cc1? Is it vaild to assume that the
offending symbol has to be both in the binding list seen when LLVMPolly.so loads
and the symbols (defined or undefined)
in cc1? Any suggestions on how to proceed in debugging this would be
appreciated.

As I said before, run once to get the address of the initializer being run
inside the dlopen call (0x100ebb5b0 in the case above).  Set a break point
there.  Run again.  When it stops at the break point (inside the initializer),
start stepping until it crashes.  You may need to step at the instruction level.

The point of the DYLD_PRINT_BINDINGS was so you can see what pointers dyld was
setting.  At some point in your trace you may be jumping through one of those
pointers.  You can check that the value makes sense and was not stomped by
something else.
