Re: 32-bit glibc build broken?

Thanks!

The i686 build is still failing for me, but this looks like a GCC bug
(I am using GCC from SVN @163591, sync'd this morning):

make: *** [/home/ppluzhnikov/glibc-git/build32/string/strstr-c.o] Error 1


However, the preprocessed file doesn't look correct either:
...
# 41 "../string/strstr.c" 2
# 51 "../string/strstr.c"
char *
__strstr_ia32 (const char *haystack_start, const char *needle_start)
{
  const char *haystack = haystack_start;
  const char *needle = needle_start;
  size_t needle_len;
  size_t haystack_len;
  _Bool ok = 1;
...
  return two_way_long_needle ((const unsigned char *) haystack, haystack_len,
         (const unsigned char *) needle, needle_len);
}
__hidden_ver1 (__strstr_ia32, __GI_strstr, __strstr_ia32);

GCC crashes on the last line (line 90). Shouldn't __hidden_ver1 have
been expanded?


Thanks,
