If I'm reading this correctly, we are invoking the Xcode gcc compiler with a
perfectly ordinary static function, and it is choking on it. The only
references I see to xstrnlen in the preprocessed file are the static function
and the calls to it.
In the assembler file I see a bunch of symbols listed as FUNCTION.eh = 0
followed farther down in the file by FUNCTION.eh:. xstrnlen just happens to be
the first. So I guess this has nothing to do with xstrnlen as such.
Looking at the command line, I'm guessing that there is some bug with the
-funwind-tables option in the compiler you are using. Does it work to compile
static int i() { return 0; }
int j() { return i; }
with -funwind-tables?
If that does not work, then I guess we need a configure test to see whether the
host GCC supports -funwind-tables with static functions.

The testcase fails with the system compiler on powerpc-apple-darwin9, which
is...
gcc version 4.0.1 (Apple Inc. build 5493)
with the same error when compiled with '-funwind-tables'...
/var/tmp//cc0vWbZP.s:65:FATAL:Symbol _i.eh already defined. Using the Apple
gcc-4.2 compiler...
gcc version 4.2.1 (Apple Inc. build 5577)
compiles the test case without errors. Testing a bootstrap with
gcc-4.2/g++-4.2.

That's strange, because GCC 4.0 doesn't have _Unwind_GetIPInfo, so the
configure test that checks for it should have failed, and it should not have
been called. Does the Xcode version of GCC have it?

I think you may be looking at the wrong thing. The libbacktrace configure.ac
only uses GCC_CHECK_UNWIND_GETIPINFO when it is built as a target library. You
are seeing a failure when building it as a host library. I don't think that
changing config/unwind_ipinfo.m4 is going to make any difference for the
failure that you are seeing.

Thanks for attaching the config.log. The config.log suggests that this
program:
int
main ()
{
return _Unwind_GetIPInfo ();
}
both compiles and links when using GCC 4.0.1 on Darwin. That would be a
surprising result, as it does not link when using the FSF GCC 4.0.1:
_Unwind_GetIPInfo is undefined. Apparently with GCC 4.0.1 on Darwin
_Unwind_GetIPInfo is defined somewhere.
Can you verify that? If that is correct, then the configure script needs to
check not only that _Unwind_GetIPInfo is available at link time, but also that
it is declared in unwind.h.

(In reply to comment #17)
Are you sure? I see...
if test -n "${with_target_subdir}"; then
GCC_CHECK_UNWIND_GETIPINFO
else
AC_CHECK_FUNC(_Unwind_GetIPInfo, [have_unwind_getipinfo=yes],
[have_unwind_getipinfo=no])
if test "$have_unwind_getipinfo" = "yes"; then
AC_DEFINE(HAVE_GETIPINFO, 1, [Define if _Unwind_GetIPInfo is available.])
fi
fi
in libbacktrace/configure.ac and it seems that GCC_CHECK_UNWIND_GETIPINFO is
only defined in config/unwind_ipinfo.m4. If so this is no longer a compile or
link test but decided by target only (see r141804).

Yes, I'm sure, because
test -n "${with_target_subdir}"
is true exactly when libbacktrace is being built as a target library. That
test will not be true when libbacktrace is being built as a host library. And
the failure you are reporting is with building libbacktrace in stage 1, when it
is being built as a host library.

FYI the test in Comment 20 passes for llvm-gcc-4.2 and clang in Xcode 4.5.1 but
only for gcc-4.2 and llvm-gcc-4.2 in Xcode 4.2. The clang in Xcode 4.2
apparently doesn't provide the unwind.h header yet...

(In reply to comment #22)
> Created attachment 28532 [details]
> proposed patch to check for _Unwind_GetIPInfo function declaration
Patch tested on powerpc-apple-darwin9 with gcc 4.0.1 which results in
HAVE_GETIPINFO being left unset and with gcc 4.2.1 which results in
HAVE_GETIPINFO being set in config.h. Also tested on x86_64 Fedora 15 which
also results in HAVE_GETIPINFO being set. Also note that for gcc 4.0.1 on
powerpc-apple-darwin9, while libbacktrace in stage 1 has HAVE_GETIPINFO unset,
it is set properly in stage2 when building against the stage 1 compiler. Also
tested on x86_64-apple-darwin11 with clang from Xcode 4.5.1 which properly
defines HAVE_GETIPINFO during stage 1.
