Hello, It is nice to see precise bug reports (though here the foo.c testcase is missing as attachment), but please check whether this is a hurd-specific issue or a generic glibc issue, as we have really much less manpower than the glibc team in general. Here it is a bug in glibc in general, and in Linux too (even if not on x86, sparc/mips/alpha have it), so please report it to the libc-alpha list.
