--- Comment #11 from stli at linux dot vnet.ibm.com <stli at linux dot vnet.ibm.com> ---
I have created a bug in glibc
https://sourceware.org/bugzilla/show_bug.cgi?id=18508
and posted a patch
(https://www.sourceware.org/ml/libc-alpha/2015-06/msg00324.html) which omits
the cfi_startproc/cfi_endproc directives for __makecontext_ret. Thus backtrace
do not find any information about __makecontext_ret in .eh_frame and stops
backtrace like it is done with _start and thread_start functions.
