# ldconfig -p | grep libc.so
libc.so.6 (libc6,x32, ABI OS: Linux 3.4.0) => 
/lib/x86_64-linux-gnux32/libc.so.6
libc.so.6 (libc6,x86-64, ABI OS: Linux 3.2.0) => /lib64/libc.so.6
libc.so.6 (libc6,x86-64, ABI OS: Linux 2.6.32) => 
/lib/x86_64-linux-gnu/libc.so.6
libc.so.6 (libc6, ABI OS: Linux 3.2.0) => /lib32/libc.so.6
libc.so.6 (libc6, ABI OS: Linux 2.6.32) => /lib/i386-linux-gnu/libc.so.6

The problem is caused by the "ABI OS" field - the libraries in /lib64 have 
higher field than the libraries in /lib/x86_64-linux-gnu/

If I comment out this piece of code in the function compare in the file 
glibc/elf/cache.c, the problem goes away and the linker will prefer 
libraries in /lib/x86_64-linux-gnu/ and /lib/i386-linux-gnu/.

Dear Maintainer,

glibc 2.24 has an ia64 bug as detailed here:
https://sourceware.org/bugzilla/show_bug.cgi?id=21672

The patch as scheduled to be merged into 2.27 is available here:
https://sourceware.org/git/gitweb.cgi?p=glibc.git;a=patch;h=01b87c656f670863ce437421b8e9278200965d38

Thank you!

Subject: [PATCH] ia64: Fix thread stack allocation permission set (BZ #21672)

This patch fixes ia64 failures on thread exit by madvise the required
area taking in consideration its disjoing stacks
(NEED_SEPARATE_REGISTER_STACK).  Also the snippet that setup the
madvise call to advertise kernel the area won't be used anymore in
near future is reallocated in allocatestack.c (for consistency to
put all stack management function in one place).

Checked on x86_64-linux-gnu and i686-linux-gnu for sanity (since
it is not expected code changes for architecture that do not
define NEED_SEPARATE_REGISTER_STACK) and also got a report that
it fixes ia64-linux-gnu failures from Sergei Trofimovich
.

	[BZ #21672]
	* nptl/allocatestack.c [_STACK_GROWS_DOWN] (setup_stack_prot):
	Set to use !NEED_SEPARATE_REGISTER_STACK as well.
	(advise_stack_range): New function.
	* nptl/pthread_create.c (START_THREAD_DEFN): Move logic to mark
	stack non required to advise_stack_range at allocatestack.c
