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.
