Bug#575351: [HPPA] This is not the bug of GCC but glibc

[NIIBE Yutaka <gniibe@fsij.org>]

I am looking the file:
eglibc-2.10.2/ports/sysdeps/unix/sysv/linux/hppa/nptl/sysdep-cancel.h

It doesn't have any cfi directives.  I think that it is the cause
of this problem.

When adding cfi directives, it would be good to add nocancel version
of functions.
